Your information will never be shared and you can unsubscribe with one click at anytime. Matt is the primary author and owner of The Everyday Marksman. With all of that said, you can see why I consider the 16 barrel to be a good all-around length, but the 20 is still king for flat shooting. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. You would like some idea of the velocity, but the only load data for the bullet weight is for 22 barrels. Great Info I got bit by the gun bug this year purchased one and built four AR15s. These represent my three favorite barrel lengths for an AR-15. This is in contrast to the original Powley constraints limiting us to more or less full loads using IMR powders. and do the work and publish your own results.

Compare ballistics data on your favorite Winchester Ammunition rounds. CPRN: CCI 32 gr. Excellent post! Its a bit harder to get exactly 36 yards. Aiming center mass means that youre likely to land an incapacitating shot from 0 to 400 yards. Its still a good general rule that a longer barrel gives you more velocity, and you can use our chart above as a reference. If were being honest, the difference between a maximum point-blank range of 296 yards and 333 yards isnt all that much. Its not an exact science, because other factors influence the velocity as well. It is a great investment if you want to get into long range shooting and will be especially useful if you handload. The short answer is yes, there can be too much of a good thing. Remember that there is a lot of friction between the bullet and the inner walls of the barrel. Also notice the 300-yard impact point. If you still cant find it, take your unloaded AR-15, and stick a rod down the barrel as far as it can go. It has not been wasted. The calculator uses the point mass method, also known as a Three Degree of Freedom Method (3DOF). Thank you for your time and effort in writing this. between polygonal and traditionally rifled barrels. Yeah I got it bad!!! I ran the numbers through JBM Ballistics and created these curves. This will be your barrel length. Theres not really a wrong answer here. The temperature of the air in degrees Fahrenheit. Small question : why does the lines of the curves not exactly match with the zero distance ? So use the data If you look closely, youll notice that the 12.5 barrel starts sending shots higher at the 100 and 200-yard points. Barrel lengths for the 12-gauge test were 22, 26, and 28 inches, and for the 20-gauge portion I tested 24-, 26- and 28-inch barrels. Even within AR-15s, muzzle velocity might be very different from gun to gun. How To Find the Ideal Twist Rate for Your Rifle, Swampfox Optics Trihawk Review: I Can See Everything.

Longer, thinner barrels will be affected by heat and will tend to . The 36-yard zero is the USMC classic battlesight zero. A .csv file is a simple text file that common spreadsheet programs (Microsoft Excel or Apple Numbers, for example) can open. If the words "solve a coupled system of first order ODE's with a numerical method" don't at least jog something loose in your memory, you'll probably not understand most of the book's math. For this exercise, Im using the same 20, 16 and 12.5 barrel lengths firing 55gr M193. If you measure the velocity of your 24" barrel, then cut it to 20", you can very accurately calculate the velocity lost. Rifles work the same way Theres simply no substitute for velocity. ), I really dig the graphs and graphics. If you would like to see the data in detail, including test methodologies, G1 & G7 BC's, form factors, variance, and other test data, we highly recommend purchasing his books.
