That being said, you have to take it on a case-by-case basis. perform. By that, I mean that the bullet would move far enough down the bore that pressure would start to drop behind it. The modifications permit estimates for less than nominal full loads and using effectively any powder. Good catch on the vertical axis subdivisions for the 300, Ill correct that ASAP. Loved this article. You got a glimpse at some of that math in my discussion of barrel twist rates. This can have a big impact on AR velocity and might be a reason that two similar length barrels have a different velocity. Hey Matt, great job getting out there! The vertical distance between the centerline of the bore and the centerline of your scope. 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. were either familiar with, or because they were what was available, and mentioning
It has all the details laid out nicely.

I'd be curious if that would add anything of benefit. A 25-yard for that circumstance would have even less offset for close distances. Barrel shape and design will also impact velocity. I dont know many ranges that let me zero my sights at exactly 232 yards. Here is one: Velocity Estimator Shooters Notes Second, one needs to get a feel for what that change means in terms of bullet drop and drift. The results are shown here: As you can see from these velocity figures measured on a chronograph at 10 feet from the muzzle, velocity is impacted very little by barrel length. Like the bound and eBook versions, the Hornady Reloading App provides all the information needed to successfully reload a variety of rifle and handgun cartridges. A 14.5" barrel would give you much less velocity than a 20" barrel, hence the problems with lethality in M855 ammo and subsequent development of the 6.8 SPC Barrel length and twist should be factored in using your muzzle velocity - Which also includes things like your actual barrel diameter. To use it, just pick a bullet from our library, fill in the appropriate information and click "Calculate".
