But that is immaterial. where v0 = initial velocity = 0, x = distance traveled inside the gun barrel, and v = muzzle velocity. 4350 is good powder. The load Ive found most accurate is 37.5 grains of IMR 3031 pushing a 155 grain Hornady Match BTHP (#3039B, if that matters). I disregard any reading that is more than 10% out from what I would expect. Ive found that it is very rare for the hottest load of any cartridge to be also the most accurate. Plus, Id never shoot an animal at that range and on targets it doesnt matter. It is paramount to calculate the correct muzzle velocity and to use the appropriate ammunition for the firearm, in order to maximize the accuracy . Copyright 2009 | Ballistics101.com | All rights reserved. Make sure target angle is set at 90 degrees. It carries no practical penalty for me because I mainly bring it out when I will be hunting from a fixed location. Since youre shooting with mils, make note of the impact. Put a night force on pops 94 youll plug hogs n yotes from a mile away just use that handy dandy ballistics calculator ignore the wind, it doesnt matter! Humidity can be simply set at 50 percent. So lets just go forward with this example. Ive shot in competition, hunted successfully out to 500m+ and have never worried about it. The kinetic energy of the bullet is the energy that is transferred to the target when hit. 5. *yikes* hope no one paid money for this advice. The average muzzle velocity of a .308 Winchester round is around 2750 fps (feet per second). The value of the stability calculator is more in comparing different combinations with each other (twist rate, bullet to be used, muzzle velocity, environmental conditions, etc.) 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). The number I am using for the acceleration of gravity is 32.16 f.p.s. Velocity doesnt matter at all. Stop it. Although there are other factors that affect terminal ballistics such as the bullet shape and type, the kinetic energy of a bullet is useful for comparing different cartridges. You are using an out of date browser. You should carefully consider weight retention and projectile expansion or fragmentation as well. by dellet Fri Oct 21, 2016 9:25 pm. charge. The estimator uses a modified form of the Powley Ballistic Calculator. However, death can take anywhere from 10 seconds to a full hour depending on how fast they bleed. Using my pet load with a 165gr Nosler ballistic tip (min expansion @ ~1800fps) over 45grains of Varget (thats a full grain below max charge) pushed to 2815fps puts my maximum expansion threshold at 550yds or so. On the other hand, Winchester Defend rounds are topped with jacketed hollow points. Wind is different across the entire trajectory . Free Ballistic Calculator. Kneel before Zod.

More about Kevin and links to his professional work can be found at www.kemibe.com. e ( CD / BC / 8816) x CV = MV. In addition, the muzzle velocity also affects the projectile's trajectory and terminal velocity. Winchesters Train and Defend line makes a perfect example. Because we dont know it is 2400 yet, we enter 2500 first. Muzzle energy is the amount of energy a bullet carries right out of the barrel. Have you ever wanted to compare a fast lightweight bullet to a slower heavy bullet to see which one hits harder? Enter the actual temperature of the day. Zero Range. Dont bother with the other inputs in that section. You are good at drawing and drew an additional 4 mils on cardboard. Modified Point Mass Trajectory Calculates a trajectory from bullet dimensions. BC = 0.300. If thats only 300 yards, thats fine, but it wont be as precise as longer distances. T/C Shockwave lists a ballistic coefficient of .240 for a 250 gr. For an overall great rifle, there's nothing wrong with the most popular barrel length of 16 inches. Now I am beginning to suspect the Chrony is more my problem than my reloading abilities.In the meanwhile, Im going to keep shooting this round as it provides the most satisfaction at the ranges I utilize it. ; Multiply the resultant with the mass of the . Aim small, miss small. Just enter bullet weight and velocity, and this handy foot pounds of energy calculator will return a muzzle energy value, in foot-pounds of energy. MOA is kind of a bitch system since there are various MOA versions. Gyroscopic stability Sg means the ability of a rotating object to resist the change of its rotating axis.

I never crimp bolt gun ammo. It doesn't have any major disadvantages in velocity and is still overall quite maneuverable. Ive found that speed isnt key to accuracy at practical ranges. Wind is different across the entire trajectorys height and range yet we can only eyeball the mirage and get one data point at the kestrel. If youve paid attention, that is 5cm at 500m, also known as one click on a mil/mil scope with .1 clicks. Thanks. The free recoil energy is the work that must be done to control the firearm upon firing. function gtag(){dataLayer.push(arguments);} Two measurements are required, the grain weight of the pellet you're using and the velocity from your Chronograph in feet per second (FPS) Enter Pellet Weight (Gr): Enter Velocity (fps): Power Output - ft/lbs Energy Expressed in Joules. FPS calc. 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. You eat your own food over there. You may add items to the list on the right in order to create a bar graph comparing the different items. Typically, manufacturers derive these numbers from data gathered using special ballistic test barrels. I never hunt with regular hunting bullets. Since the AR-15 rifle is such a highly customizable gun, there are various features you can change which impact muzzle velocity, and we'll examine them below. There isnt anything a 13 .308 cant do. The muzzle velocity of the CCI Stinger Ammo is 1,640 fps compared to the . 00:02 12:50. 3. If I was having a rifle built it would wear a 22 barrel, and experience shows I would still be carrying a nearly 300fps advantage over a 13.5 barrel. Although we dont always like it, a hunter can shoot an animal and let it run off a short distance to expire. This is just about how I zeroed my McMillan .50.

None of that cant garbage needs to be worried about in real life. We find it highly valuable and worth the price. Form factor = 0.719 Muzzle Velocity (ft/s) Muzzle Velocity: Actual muzzle velocity corrected to the muzzle from the chronograph location. A $3000 scope and all that mumbo jumbo is easier than buying a $150 chronograph? This is the number placed into the ballistic computer as your muzzle velocity. Firing under anything other than Standard Metro conditions changes the effective ballistic coefficient of the projectile (from Sierras 6th Ed). Plug the acceleration, displacement and initial velocity into this equation: (Final Velocity)^2 = (Initial Velocity) ^2 + 2_(Acceleration)_(Displacement). The second one isnt super critical, but just get it correct. In order to determine the kinetic energy, you must know the velocity of the bullet and the weight of the bullet in grains. Every fanboy seems to want to throw in humidity and Coriolis like theyre trying to impress someone, but it matters so little in real life at realistic ranges that its just safe to set it at 50 percent all the time. What? Theres a reason that computer guided optics are becoming a thing these days. This muzzle energy calculator should prove pretty useful in a wide variety of applications. Bison Ballistics Munitions, LLC That said, Ill elaborate on how to maximize your accuracy with a standard duplex reticle but it wont be easy. 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 my example, I will be using data from my .308 load of choice, which is a 168gr Hornady HPBT, Lapua brass, CCI 200 primer, and 43gr of Varget. CD = 7 feet.

Go buy Magpuls Art of the Precision Rifle. Muzzle Energy is useful in comparing cartridges, calculating recoil, and stopping power. Also look at H-110. Math is irrefutable and forces you to accept facts. Help me identify this beautiful flintlock rifle, please. Dissing long range just because its impractical for hunting or target shooting is not a valid reason to dismiss the need for sufficient velocity. Muzzle energy isnt exactly precise or the most important aspect of ammunition performance. BOOK VALUE for 2F, 24-inch barrel at 80 grains is 1560 FPS. Muzzle velocity and energy are often stamped right on ammo packaging. .. Also, you say twist direction and rate are important but sight height isnt. You may not have mils, but you do have a Sharpie. Is it actual MOA, like 1.06 at 100 yards or is it 1? A shooting chronograph is a tool that measures the speed at which your bullets leave the barrel of your gun. We had three high velocity loads that measured close to 1300 feet per second - The 40-grain copper plated round nose version of the CCI Mini-Mag , the 40 . Notify me of follow-up comments by email.

Now that you know thats 3 mils, hold those 3 above the target and off to the side. Im loading 308 for AR-10 and 30-06 for a bolt. x and y are horizontal and vertical displacement in meters (m), t is time in seconds (s), a is acceleration in m/s2, and g = the acceleration due to gravity on Earth, 9.81 m/s2. I have a real-world rifle for real-world uses and it still does .1mil at 100m all the way to 1000m and Ive used it on animals and targets alike without issue. No amount of calculation is completely accurate. Too fast. In words, the bullet energy KE (in foot-pounds) is equal to the bullet weight (in grains) wb times the square of the bullet velocity v (in feet per minute) divided by 450,437. In just a few seconds, an attacker can carve you up like a Christmas ham and leave you bleeding in the street. Instead, it is a rather ethereal figure that can only be computed using the previously mentioned formula. There isnt any shame in missing. Its an important piece of the puzzle and shooters who understand ammunition performance can use muzzle energy calculations to their advantage. BC and MV are just inputs for generating trajectory (drops), and youre working from actual drop, so . (Heres that disclaimer I promised) I will be the first to admit that a 26 barrel is pointless on a 308, but thats how my rifle came from the factory, and to the extent I have hand loaded for it so far it shoots lights out so I am inclined to leave it be. I guess I am going to be the guy that gets bunched up on your velocity/caliber claim. Who are we? For self-defense and hunting ammunition, muzzle energy is just part of the equation. Change barometric pressure or temperature and all that work is for naught. You literally cannot avoid it. Thats not nothing. Sure you want a hard-hitting round to ensure adequate energy transfer and penetration, but you also need to consider bullet design. HANDGUN BALLISTICS. Velocity - The velocity in fps at that distance. where v 0 = initial velocity = 0, x = distance traveled inside the gun barrel, and v = muzzle velocity. 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 . Those unknowns will make the outcome of the program into just a guess. When talking about bullet kinetic energy, the word muzzle energy is often brought up. You need to pay attention to velocity in two aspects, and they are: Doesnt this mean your method of attaining MV may yeild a wrong value for MV? Enjoyed your enthusiasm . 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.
