shorter barrels are always louder because the muzzle is closer to your ears!!! Because the sound as measured at the barrel is louder in the short barreled gun. The amount it is reduced by holding it further away does not completely counter act the extra noise it is producing.

In a typical recoil situation, the release of a body of smaller mass (body 1) has an impact on a larger body (body 2). If both bodies start from rest, the law of conservation of momentum states that m1v1 = -m2v2. The recoil velocity is typically the velocity of body 2 after the release of body 1. This velocity is.

The recoil won’t hurt, and at most, it would sting you. But the excitement may drown that stinging down. You might also require little adjustment after. You can practice stability with your gun after a few more shots.

In theory, shorter barrels are more accurate. Tolerances are more difficult to hold over longer distances. Shorter barrels also are relatively stiffer for the same profile, and so the harmonics are easier to work with. Once you get past 100yd benchrest, barrel lengths start creeping up.

Belief: Now that we know that accuracy is pretty much the same, short barreled rifles lose too much velocity be effective at long ranges. That is only a decrease of around 315 fps from the 26 inch length (25.2 fps/in), and vindicates many researchers who pioneered velocity discussions.

Velocity matters in terms of physical recoil; F=MA, after all…but it’s less of a factor than you’d think. In other words, velocity does affect recoil but an increase in velocity has less of an effect than an increase in mass does. More gun = more mass = less recoil force being transmitted into the shooter.

Longer barrels give the propellant force more time to work on propelling the bullet. For this reason longer barrels generally provide higher velocities, everything else being equal. As the bullet moves down the bore, however, the propellant’s gas pressure behind it diminishes.

Theoretically 16″ barrels are more stiff than 20″ thus more accurate. However barrel quality will always trump length. longer barrels will be more accurate at longet ranges but no big difference between my 14.7 and 20″ at 100 yds.

By using a 16 inch barrel, you are going in the wrong direction, velocity-wise. You will be able to do quite well to 4 and maybe 500 yards. You will also get hits at 600 and longer, but the term “group” will more likely be supplanted by the term “pattern” or “chance meetings.”

24-27″

This experiment has been done by cutting down very long barrels, and the result is that most modern cartridges will spit bullets at the highest velocity from barrels at least 36″ long. tl:dr; Longer than you can probably put on a firearm, and too long to be practical for anything other than experimentation.

The short answer: Yes, a longer gun barrel improves accuracy. Theoretical accuracy of handguns and rifles is driven by rifling, barrel length, and bullet mass. Therefore, a longer barrel increases the exit velocity of the bullet and the effective range of the bullet.

The 350 gets over 23% more penetration than . 243 Win and 60% more than . 223 Rem. It even has over 14% more energy than 300 Blackout, 15% more than 30-30 Win, and 49% more than .

22 inches

A 150-yd. zero is pretty much perfect for 350 Legend, using any of the three above hunting loads, and either a 16″ or 20″ barrel; impacts will be between 1″ to 2″ high at 50 yds., between 1.5″ to 2.5″ high at 100 yds.

26 or 28. You lose very little range and power with a 26 inch barrel. The only advantage that a longer barrel has it that is is easier to swing.

A cheaper barrel might last 2500-3000 rounds where a higher end barrel might go 4000+ rounds before crapping out, which often correlates to the original cost of the barrel.

Residual fouling buildup: Each bullet that passes through your gun creates fouling residue in the barrel. The residual fouling can build up in the barrel, affecting your precision and potentially your handgun’s reliability. Failure to fire: Failure to fire is a common issue with guns that don’t see regular cleaning.

20,000 rounds

Tribe claims that the semi-automatic AR-15 can fire “over 10 rounds per second.” According to the Bushmaster AR-15 manual, the firearm has a maximum effective rate of 45 rounds per minute — a far cry from the number touted by Tribe. Competitive shooters can fire at a maximum of three shots per second.

Competition pistol barrels are known to discolor from heat. That takes about 500F so you can get a barrel pretty warm without short term damage.

After around 500 rounds (more or less), the rifle would start experiencing “feed/jam” problems, probably because of the powder. I would recommend cleaning it every 1000 rounds OR LESS, but only if you want to be sure it will keep functioning reliably.
