Fire again twice. Contact Us. When you have it zeroed, find the longest distance you can possibly fire at. I dont trust chronographs but I do trust math. Stopping power has plenty more factors than simple kinetic energy. The 175 grain Eagle Eye loads I use do 2,620 out of my 20 LTR. The .308 is good to a mile. + .7 inches at 50 yards, 0 at 100 yards, -4 inches at 150, and -12.1 at 200. Aim small, miss small. This is why soldiers and police officers are trained to aim for center mass, it increases hit probability even though an instant kill is highly unlikely. Crimpled ? The 150-grain bullet has a muzzle velocity of 2,820, while the 180-grain has a muzzle velocity of 2,620 feet per second. Muzzle energy is increased if you increase mass or velocity. Its easy to understand why we get so deep into the numbers. Tape or glue a bunch of cardboard together and secure it to a bermsomehow. 4. Never go full metric. BC and MV are just inputs for generating trajectory (drops), and youre working from actual drop, so . One foot pound (sometimes written as ft-lb) translates to the amount of kinetic energy it takes to move a one-pound object one foot. Thats not nothing. Well, one thing you can do is use our bullet comparator tool to see what the differences in ballistic performance is likely to be if you switch bullets. Data points can be expanded on by altering variables from a constant. Exit out and be sure to accept your MV. Ive found that speed isnt key to accuracy at practical ranges. Its far more complicated than high school math, even if that sometimes feels like the most complicated thing on planet Earth. The benefits offered by a that kind of scopeare literally too many to list. CV = 1500 fps. Let MV = The Muzzle Velocity calculated from the Chronograph Velocity. Pellet Weight: Grain. Muzzle energy is a prime comparative figure and could be the reason you pick one load over another. While deep penetration is great for reaching vital organs, too much penetration can cause the bullet to pass completely through the target, taking that energy with it. You still dont know jack at the end of the procedure. Dude calm down aint nobodys advocating killing american LE and MIL when there is not a revolution going on. You will learn more than I have time to write on this page. wisdom vs. experience or, today I learned What Muzzleloading Stuff Did You Do Today. Go buy Magpuls Art of the Precision Rifle.

So I am not only confused and perplexed by this, but am wondering just what it is Ive been attempting to understand all these years. A large target , painted flat white rigid cardboard or plywood , about 4 x 8 . Removing margin of error is preferable to claiming superiority based on simplicity. What should come first:consistency. Group size at 100 yards is just under half an inch in both directions (horizontal/vertical), so I say its half an inch. You'll need to Sign In or create a Ballistix Account if you'd like save your calculation data. One of the downsides to using a ballistic calculator is the before vs. after effect. Dont touch your elevation knob no matter what range youre shooting. As I learned at Pecos this year, a 10% difference in score is the difference between placing where Tyler placed (in the top 10) and where I placed (somewhere a good bit lower than top 10). gtag('js', new Date());

.. Also, you say twist direction and rate are important but sight height isnt. To understand this, think about how hard a baseball would hit you when tossed by a four year-old versus its impact when pitched by Randy Johnson. Do not do that. Granted you can shoot 20 rounds to walk that 13 308 into the target at a mile and hit all day long, but i found my 20 375CT with better BC and higher MV makes it much easier. I supposed someone could put the numbers in Excel and the program would "calculate" the #'s for you basically by just doing the math. Lemme give you one practical application for 1000+ shooting: killing govt goons when the 2A is finally applied into real use, which is why we own guns in the first place. The more complicated answer: Muzzle energy is the measure of kinetic energy a projectile carries when it . Ive been hunting with Hornady 168 HPBT match bullets for years and Ive never had an issue. For my abilities and shooting the El-Cheap-o rifle I am, I think its excellent. You are good at drawing and drew an additional 4 mils on cardboard. Leave it.

For me, they are at 5.1 mils low of a 100m zero at 500m. Our Friends Below are some common foot pounds of energy (fpe) readings for common calibers and common bullet weight combinations. Save my name, email, and website in this browser for the next time I comment. Since my long range shooting primarily revolves around hunting, velocity also matters quite a bit where your bullet has a specific velocity threshold where it will expand and disrupt tissue as opposed to turning into a copper and lead ice pick, and your deer runs off to be eaten alive by coyotes. Youve just proven your immaturity to every sane person reading this. Just right. v^2 = v_0^2 + 2ax v2 = v02 +2ax. 22 LR Muzzle Velocity: 22 long rifle muzzle velocity is the speed with which a bullet leaves the barrel measured in feet per second (FPS). Mils are stoopid. What We Use All the ballistics from all manufacturers, finally in one place. In order to determine the kinetic energy, you must know the velocity of the bullet and the weight of the bullet in grains. What matters more is what the projectile does once it strikes the target. Pressure and temperature is different when the max ord is dozens of yards above sight line and this is assuming you are not shooting across a valley. But bolt gun? Thats how velocity affects muzzle energy. 1. So no matter how fast a bullet is fired, it is falling toward Earth just as quickly as if it had been simply dropped from your hand. You get the drill. The calculation is done with the same program as the trajectory page above. The heavier the bullet and the faster it moves, the higher its muzzle energy. What would YOU DO if an Airsoft Ref came up to you like this? . Also look at H-110. Thanks for the work . Actually look down your crosshair and see where the mil lines are. Because velocity has such a huge impact on muzzle energy, anything that affects velocity also affects energy exponentially. This number can be used to get a rough idea of a round's destructive potential. A decent scope that you learn thoroughly , I prefer a Quantum VX -2 4-1250 on my long range rifle . It takes into effect things like atmospheric conditions, wind, and even allows you to make projections shooting both up and down hill. inches. So what do us normal guys who dont try out fifty handloads in one sitting do? The bullet is whats true. The 300 Blackout's .30 caliber bullet can be made especially long, and as the result may weigh up to 220 grains quadruple the weight of the typical 223 Rem round's. So heavy a bullet conveys a subsonic muzzle velocity and correspondingly softer report. I have been fortunate, for the two main loads I shoot in this rifle I have found good accuracy nodes on the higher end of velocities, but without having to run at max charges or push pressures. It is left set at the default of .5. This system pairs range-ready Train rounds that are perfect for practice with Defend rounds engineered for terminal performance. The best and easiest way to do this involves shooting at dirt and steel and then at cardboard. Because we dont know it is 2400 yet, we enter 2500 first. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. Muzzle Velocity. If youre shooting at 849 yards, .1 mil is equal to 8.49cm and so on. I have a responsibility to this site to tell the truth about guns, and sir, the truth is I wont write what I truly feel about you because I wont stoop to the strata you occupy.

The way I read the OP, he is asking if there is a program that will give velocities based on black powder loads. where v 0 = initial velocity = 0, x = distance traveled inside the gun barrel, and v = muzzle velocity. There you have it. Trust me when I say that Ive been teaching people for years and this method is what I use to instruct at the range. They perform the tests in a controlled laboratory environment. Muzzle Velocity Calculator Ballistics Calculators Diameter (in) Weight (gr) Ballistic Coefficient (G1) Sectional density = 0.226. This will make the feel and point-of-aim comparable. I had not thought much about that before. just because it's impractical for hunting or target shooting is not a valid reason to dismiss the need for sufficient velocity. . If an object is moving, it has kinetic energy. The OP is asking about internal ballistics of black powder and round projectiles. There is nothing to look at except for the last yard line. EDUCATION 101. Ive found it to be very consistent. Remember, Targets4Free.com is your number one online source for 100% free targets, as well as resources like this one! In hunting terms, stopping power more accurately refers to killing an animal as quickly and humanely as possible. Do that at any range you have and then print off your data. Calculating Muzzle Velocity and Trajectory With Five Shots (Or So). If you click one of these links before you buy, we get a small commission while you pay nothing extra. Here goes: velocity isnt important. Note that these equations are independent of mass and do not take into account air resistance, a common qualification in simple physics calculations. To calculate the muzzle velocity, a velocity measurement, the ballistic coefficient and the distance from the muzzle to the measurement point are required. (Thats 10cm at 1000m for those of you that measure in Freedom Units only.) At 2400fps, my bullet makes one hole at 100m and .1 mil accuracy out to 1000m. Bullet Weight. You are trued - easy day! Click Here to open in small window. I printed it out just the same . Firearm Setup. There is no sight height, no bullet weight, and no muzzle velocity because Marc doped gravity, not a set of specific conditions. If the mass m and muzzle velocity v of a bullet are known, its kinetic energy and momentum can be determined from the relationships Ek = (1/2)mv2 and momentum p = mv. Or more. Lyman found that barrel and load would give about 1573 fps muzzle velocity. I agree with your short&thick=rigidity=PRECISION. What Barriers Do To Ammunition Testing Data, The Best Self Defense Ammo Ballistic Testing. Help me identify this beautiful flintlock rifle, please. But, it shouldnt just be tossed aside. We also collect information about your rifle scope so we can provide you with compensation results specific to your scope's make and model. The factual truth is that velocity & BC do matter. On your calculator, enter the following, being sure to enter the parentheses " ( )" characters in the equation. Dont believe me? Wad weight (gr) I like the method for establishing drops as well, I dont always have access to a chronograph and this will likely be a valuable tool for me in the future. JavaScript is disabled. You should always pick the load that gives you the best results. Is there a calculator out there somewhere on the interseine for estimating black powder velocities? Weight. Joined: Fri Nov 30, 2012 6:25 pm. I forgot to mention that I also have shot .300 BLK out to long ranges and found the hits to be easy to make. However, the Train rounds would be a poor choice for loading your concealed carry weapon. Blackhorn 209 posts 1,900 fps of muzzle velocity for 100 gr. Remember, it isnt about speed or barrel length. I disregard any reading that is more than 10% out from what I would expect. I never crimp bolt gun ammo. So lets just go forward with this example. For example, if you double the velocity of a projectile, the muzzle energy doesnt just double, it quadruples. I find I get my best prone and offhand done at that distance. Ooooook, Yeah, but you get much more use out of high quality glass than a chronograph that will wind up shot, sooner rather than later. What? Select your ammunition to prefill the following data attributes or enter your own values. . There isnt anything a 13 .308 cant do. But that is immaterial. Enter Weight: grains: Enter Velocity: feet per second . Use the calculator below to calculate the kinetic energy of a bullet.

Firearm muzzle velocities range from approximately 120 m/s (390 ft/s) to 370 m/s (1,200 ft/s) in black powder muskets, to more than 1,200 m/s (3,900 ft/s) in modern rifles with high-velocity cartridges such as . Dissing long range just because its impractical for hunting or target shooting is not a valid reason to dismiss the need for sufficient velocity. You may add items to the list on the right in order to create a bar graph comparing the different items. For a game animal or a human attacker to die, there must be sufficient blood loss, usually through significant damage to the vascular system or a major blood-bearing organ. Bullet Properties. Next Post . Form factor = 0.719 Muzzle Velocity (ft/s) The website will also let you include a zero at Point Blank Range, which is great for guys with the duplex reticles. The ballistic performances for the 7mm-08 Remington based off a 24 inch test barrel on two grain types for muzzle velocity are 2,800 ft/s (140 gr Nosler P), 2,650 ft/s (150 gr Speer HC-SP). Thats .1 mil at that distance, which makes 1 mil equal to 50cm. It will a produce a line graph showing the bullet drop and flight path of the bullet. Those were the CCI 40-grain Polymer Coated Clean-22 and the Eley 38-grain Subsonic Hollow Point . Your chronograph is most likely the problem , there is no way youre getting 500fps diffs with the same powder and loads on the same bullet . To calculate muzzle energy, or Foot-Pounds Equivalent (FPE), you need to know the mass of the item being moved and the velocity it will be . The muzzle velocity of the bullet. I like their stuff because I get it, but I have a hard time agreeing with some of their ideas. Many gun people will even use the term interchangeably with stopping power. But is muzzle energy important? I push 2815 fps with a similar load to the one you mentioned out of my 26 308 (disclaimer on that in a second). For guys who dont have first focal plane mil/mil scopes, the going is a bit tougher because you have no clear demarcations on your crosshairs and no ability to easily gather information. Here we specifically present the form these equations take in the case of projectile motion. Even the factory loads that produce the best accuracy from this rifle are very inconsistent in their velocity and this really surprised me! the muzzle). One frequently hears the expression describing an . Quality consistent ammo that your rifle has already eaten well . It allows you to estimate velocity based on your current zero and the amount of drop at another chosen range, say 300 yards. Use this ballistic calculator in order to calculate the flight path of a bullet given the shooting parameters that meet your conditions. charge. Comments like this are why people dont like this community. At best it should be considered a rule of thumb or an estimate. Your 308 load moves approx 46 more at 1000 yards than my .260 load in a 10 mph wind. Go back to the range or set your cell phone down and set up a target at a random distance300 yards900whatever. You will see the Kestrel calculate a new muzzle velocity. You can calculate kinetic energy using the classic formula you memorized in Physics class. The standard deviation (aka "SD") is a measurement that shows how much variation from the average number exists in a sample. Fire. Ballistics Calculator. Who are we? Chances are good that youve had to follow a blood trail before recovering game. Max Range: The furthest distance you want to be represented in your trajectory output. Enter the Energy (Joule) results from the FPS and Velocity calculator in the "Input 2" field along with your BB weight in grams. Muzzle velocity changes to an estimated amount of fps. There will be a day when even a FFP mil/mil is obsolete, but were not there yet. where v0 = initial velocity = 0, x = distance traveled inside the gun barrel, and v = muzzle velocity. Any bullet that even nicks a vital blood vessel will do the trick. 300 Blackout, not just for sub-sonics. The average muzzle velocity of a .308 Winchester round is around 2750 fps (feet per second). Muzzle energy is the amount of energy a bullet carries right out of the barrel. Josh- Two things puzzle me. Because P = F/A, F = ma, and the area A of the cross-section of a cylinder (which a gun muzzle can be assumed to be) is r2 (r being the radius of the muzzle), a can be expressed in terms of these other quantities: Alternatively you could get a rough estimate of the bullet's velocity by measuring the distance from the muzzle to a target and dividing this by the time it takes the bullet to reach the target, though there will be some loss due to air resistance. QuickLOAD software is an internal ballistics package that will allow you to estimate muzzle velocity and a whole host of other things (like chamber pressure and barrel time) based on detailed inputs (powder, charge, case dimensions, bullet dimensions, etc.). For example, if we know our 185 grain bullet shoots at 2,775 fps out of our rifle, and we'd like to estimate the velocity of a 200 grain bullet we'd like to try, \(v_{known}\) is 2,775, \(m_{known}\) is 185, and \(m_{new}\) is 200. Previous Post. Its a game when its on paper for score, not life and death. Muzzle Energy is useful in comparing cartridges, calculating recoil, and stopping power. I really love what my stubby barrels are doing for me. Just enter your bullet weight below and its velocity. Typical handguns have muzzle velocities in the range of 1,000 ft/s, which means that such a bullet would travel a mile in a little over five seconds if it hit nothing or did not fall to the ground by that point. Skip down and change the units to mil in the first column and to centimeters @100m in the second one. It's a quick and dirty sanity check if you're thinking about trying a new bullet and want to know about how much velocity you will gain or lose. Data entry. Gravity pulls a .22 the same as it does a 338, so having put a value . The real variable in long range shooting is wind, nothing helps you negate its effects better than a high BC bullet with good speed. Now, I'm not saying Lymans data is right but I've fired a lot of shots out of a .50 caliber TC using a 80 grain 2Fg powder load and they always "crack" when their shot. Free Ballistic Calculator. The free recoil energy is the work that must be done to control the firearm upon firing. Continue reading if you want to understand what projectile motion is, get familiar with . To use the calculator, simply fill in the input values (blank white boxes) in the large black box. Different brands and batches of blackpowder will vary and that can't be put into the program because it won't be known. $$v_{new} = \sqrt{m_{known}v_{known}^2 \over m_{new}}$$. Your group sizes can open up. So, as the title says, how does one go about figuring things out with only five shots? b) how consistent is your muzzle velocity? Simple is not always better and when it comes to making hits and winning matches, I dont ever want to walk rounds on. Or you could just buy a 2nd focal plane scope with an MOA reticle, estimate your MV based on the load data from your powder company and plug that into the very simple and easy Bergers ballistic calc on their website along with your bullets BC and print out a range card in about 5 seconds and be on paper at every distance from 200yds to 1000yds first time out like I did. If youre really careful, you can actually take that permanent marker and draw mils on your glass. Distance from measurement point to muzzle (yards), Ballistic coefficient (G1) under standard conditions, Free recoil energy of the firearm (ft-lb), Barometric Pressure: 750 mm Hg = 29.53 inches Hg. Generally a good idea to avoid speaking in absolutes, on top of that, categorically stating that velocity doesnt matter is a bit misleading. Im shooting .308 Winchester out of a 26 inch barrel (but that is immaterial). Great read, where in West Michigan is there a 500 meter range? I may try switching to H4350 where I was using H414. Use your imagination. By using these equations, you can determine the path of a fired bullet and even correct for drop due to gravity when aiming at a distant target. Thats a 40% decrease in effective range. Ive seen a lot of conflicting advice regarding crimping for the AR-10, both as to whether or not its really necessary and if it really affects accuracy. Using holdover I was able to figure out to aim 11 inches high with a Ruger semi auto .44 mag @ 200 yards, talk about slow velocity, fire gun, 1 wecond silence and then whap. Zero Range. It is paramount to calculate the correct muzzle velocity and to use the appropriate ammunition for the firearm, in order to maximize the accuracy . What's A Typical .308 Winchester Muzzle Velocity. This calculator is a simple estimator. ; Find the product of mass and velocity of the powder charge. And Im trying to figure out how/whether the ballistics you generate are correct regardless (wrong MV, wrong bc, correct drops), which must be true since it works.
