The Purpose of a Pistol is to get you a Rifle!!!!!!!!!!!!!!!!
I subtracted 25 fps per inch until I reached the desired barrel length.” Wrong, Hornady’s published velocities for 300 BLK are for a 16-inch barrel, while Hornady’s published velocities for .223 are for a 24-inch barrel, and Hornady’s published velocities for 5.56 are for a 20-inch barrel. Rather than pondering raw velocity numbers, think about your application.
No.If you are shooting .22 caliber/5.56mm (and when did real Americans start using metric units?) Moral of this story; check links to identify round used, and use 5.56 over .223 for FMJ/cheap ammo. over what ammo or caliber or gun is "best."

You’ve put in a lot of money and time to get a cool tool that you would bet your life on. By the time the bullet gets to the end of a 20-inch barrel, the volume …
It is combersom and very hard to conceal. And there have been many tests in handguns of those calibers, but I haven’t seen a lot in longer platforms such as ARs. While it appears that the M855 (62gr) and M193 (55gr) had nearly identical velocities, this should be physically impossible considering the weight difference in those two projectiles (all other variables being held equal). The round and rifle have both proven themselves in the last 50+ years, and the debate (mainly) has been put to rest. CPHP Stinger: Remington 33 gr. If you shoot the same bullet from a 16-inch barrel, you’ll all below 500 foot-pounds at 375 yards.
At some point along the barrel length spectrum, you’ll start to get less velocity.
up to you. Actual wound damage is what most people want to know for selection of defenseCheck the AE 55 grain link in the article. Oh the stories…He still got it right when he viewed Obama as an unwired ass.No criticism of the shooter, however, is there any explanation as to why the 16 in barrel could barely manage a sub-5 inch group at 100 yds?
then the expansive type for direct contact. mostly) paid for everything ourselves, and we did not receive any kind of sponsorship With the subsonic load, there was only an 80 feet per second total loss or about 10 feet per second per inch.While I was at it, I decided to do some accuracy comparisons. or remuneration from anyone.
Arrogance over competence. Drywall is not going to readily precipitate fragmentation unless the round is penetrating multiple barriers. How is that possible?
The 5.56 was designed for the M16, which features a 20 inch barrel, and the bullet uses all of this length to get up to a velocity of 3,000 feet per second.
I’d like to see that rule of thumb tested.3. No matter what you carry though testI have several ars, and a pistol, 10 inch barrel that has a specific purpose and place.
Admittedly, that’s a weak theory. I’d guess that particular one is just a slightly smoother and polished bore than the other two.To me, the big learning is that the 16-inch barrel, with a whopping four inches shorter length, was just as accurate as the 20-inch version when using quality match ammunition.I’m not the only one to observe that extra barrel length really doesn’t improve accuracy on its own. was/is a good stopper, it appears that politicians and bean counters will prevail again with the 9mm. That is interesting, and supports the theory that once a bullet is stabilized in the first few inches, the rest doesn’t really matter. A significant velocity difference would be expected when moving to a 20″ or shorter semi-auto rifle.As to the article’s premise, barrel length is a lot like barrel twist rate. We’re not English, the English use the metric system and still will after Brexit, we’re not an empire and we have t been part of the British Empire since the Treaty of Paris.Moreover, it’s just a measurement system, not a prof of manhood nor a loyalty test. The 20″ M16 had slow twist and a “ton” of crap restraining barrel vibration and accuracy.
For starters, if I were to need to use my weapon in a defensive situation, it would be close quarters, as anything farther would warrant Escape and Evasion maneuvers, in which an SBR would be more handy. Or not.
Optical sights eliminate any sight radius factor.
