The term 'rifle' comes from the fact that the barrel of a rifle has spiral grooves (called rifling) cut into the inside. When the bullet is fired it is forced into these grooves which in turn cause it to spin as it travels down the barrel. This spin around its long axis creates a gyroscopic effect which stabilises it in flight dramatically improving its ...

In the U.S. there are legal definitions provided by code (18 USC 921) and regulation (27 CFR 478.11), which are somewhat derived from the customary definitions. A shotgun is designed to shoot shot (i.e., multiple ball projectiles) through a smooth bore. Yes, you can buy rifled shotguns designed to fire a single projectile, but they still shoot shotgun ...

Absolutely safe. The .357 Magnum cartridge was literally designed as a high-pressure .38 Special: Max pressure on a .38 Special is 17kpsi (with the +P specification allowing for 18.5kpsi). Max pressure on a .357 Magnum is basically double: 35kpsi. In order to prevent people from putting the high-pressure rounds in a gun not designed for them, the ...

Most gun ranges will accept live ammunition for disposal in my area. I would check there, and if not there, a police department would be my next stop. This answer probably only works in the United States, I am not sure about abroad, and as a commentor pointed out, outside the United States, and especially in Europe, you may be finding military unexploded ...

A .357 Magnum can safely and readily shoot the following rounds: .38 Short Colt, .38 Long Colt, .38 Special, .357 Magnum. Your big problem in the short-near term is that shooting shorter cases will foul cylinders further back in the chamber and if not cleaned thoroughly after shooting, you may not be able to seat longer rounds from baked on carbon build up. ...

Assuming both the 40 and 60 grain are actually subsonic (the projectile does not break the sound barrier) and both have similar muzzle velocities, you should expect the 60 grain to be louder. It takes more energy (gun powder) to get the heavier 60 grain projectile to the same speed as the lighter 40 grain projectile.

The long and the short of it is no - definitely not. If you check wikipedia (or other reputable sources such as SAAMI) you will see that the parent case of the .38-40 is the .44-40 Wincheseter, which on the face of it makes them completely incompatible. To see why these rounds are actually incompatible you can search the SAAMI specifications for the .38 and ...

No, I don't believe so. The .38-40, perhaps despite its name is a 40 caliber round, while the .38 Special, certainly despite its name, is a much smaller .357 round. The case diameter dimensions are also much smaller, so a .38 Special round is unlikely to fit properly in your rifle. In addition, it's generally considered to be a bad idea to fire modern ...

You are referring to duplex loads. I don't see a whole lot of duplex loads anymore unless its a mix with TSS (tungsten super shot – the densest shot available). Remington had a line of duplex loads that featured a mixture of 4 and 6's. The reason stated was the #6 shot would provide the pattern density and the 4 would provide more penetration.

The distinction between rifle and shotgun can get convoluted if only considering shot vs single projectile. Shotguns can be loaded with rifled slugs, rifles can fire shot shells. CCI has marketed shot shells for the 22LR, 22Mag, 9mm Luger, 40S&W, 44 Mag, and probably others (those are just the ones I've bought). Yes, I've seen and/or owned rifles in ...

Put a strong magnet on top of a shell and turn it upside down. If the magnet sticks then you know it contains steel shot. If it doesn't, then you could have either lead or "non-toxic" shot. If you paid less than $10 for the box, and/or the box doesn't make a big deal of stating that it's non-toxic, then the shells almost certainly contain lead shot. If ...

The density (weight) affects ballistics. Less dense shot will slow down at a faster rate. Lead is a relatively cheap high density metal but is has negative health consequences. Tungsten is dense but it is expensive. Steel is commonly used now and is less dense than lead. Wind resistance is only dependent on size and velocity. A heavier shot ...

"Buck and ball" loads are commonly available. They're often marketed for self defense, but where legal for hunting they have the same benefits on game, namely: The "ball" (or slug) has more reach for aimed shots on further targets, but if you happen to get a closer-in target you have the "insurance" and added stopping-power of the buckshot.

The standards are set by SAAMI (Sporting Arms and Manufacturers Institute) and it depends on the type of firearm. Rimfire rifles 24 inches (page 60) Centerfire rifles 24 inches with 5 exceptions (page 231), 7.62x39 – 20.00 inches (508.0mm) 30 Carbine – 20.00 inches (508.0mm) 300 AAC Blackout – 16.00 inches (406.4 mm) 350 Remington Magnum – 20....

I've worked extensively with the Aguila subsonic .22LR loads. Out of a full-length (i.e., 18") barrel the 40gr runs about 1035fps while the 60gr barely breaks 900fps. So both are soundly subsonic. The 60gr is an unusual load in which the bullet is crimped in a .22 Short case. It's easy to recognize, in contrast to the 40gr which looks like most other ....

I believe that the term presence of Rifleing in the bore defines the weapon as a rifle, even big caliber guns on Naval vessels are termed rifles. Barrel length defines a pistol, it is really a short barreled rifle with >16" length barrel (by FFA 1934) in the USA and or designed to be fired easily with only one hand and easily concealed. The construction ...
