So, if you're a total newbie, and you're a little confused about what some people say about. That way, you can safely operate such firearms while using multiple calibers. To explain WHY a. The projectile is seated with a bullet in the chamber. The bullet is almost as big as the inside of the barrel. When the cartridge is discharged, the propellant powder in the bullet creates pressure behind the bullet, pushing it out of the barrel.
How the bullet seats in the gun is called "headspacing. Revolvers headspace on the rim - the rim of the cartridge is flush with the cylinder - and semi-auto pistol cartridges headspace on the case mouth, the lip of the case that the projectile the bullet is seated into. Shotgun cartridges headspace on the rim as well.
Many - but not all - rifles headspace on the shoulder, the part of a rifle cartridge where it tapers toward the projectile. Many don't, though; many semi-auto rifle designs headspace at the case rim AND the shoulder. Older rimmed rifle cartridges often headspace on the rim. Revolvers universally headspace on the rim, and the.
That said,. Unless you don't like having hands, don't do it. This is by design; when the. And that is the idea with any gun that's said to or actually can fire multiple calibers. However, other guns are not. What's been discovered over the years is that a number of different chamberings can actually headspace another cartridge, sometimes with a little force Typically it starts with someone who heard that you could shoot X through a gun made for Y.
Again, in some cases - such as. The best-case scenario is that the shooter has errantly chambered a round that can safely headspace in the gun, but the projectile is smaller than the bore diameter. For instance, if someone has - in error - placed a.
In this case, the projectile will leave the barrel at a very slow velocity as most of the gas has already gone out of the barrel. Accuracy will be almost nonexistent and that's pretty much it. The worst case scenario is if the projectile is larger than the bore or if the cartridge doesn't completely headspace but the action closes anyway.
In this instance, a catastrophic malfunction will result. The bullet can completely split the barrel if you're lucky in the first case, but otherwise this will result in rupturing the chamber. In other words, kaboom. First, by knowing what guns or calibers truly do allow for safe use of different calibers, and they are few, and exactly how that works.
In other words, the way things are. Second is by understanding how and why that's possible in those instances, so you understand why things are the way they are.
Thirdly by not taking chances based on what people tell you. If you hear something from someone, look it up. If you don't find information confirming it, don't do what they're suggesting. So, what are some common examples? Here are a few common ones. There may be some uncommon ones, but we can leave them for another time.
The differences between. In other words, 5. Now, what does that mean? However, it also means that 5. Therefore, using 5. However, using. The same is true for. Different chamber length and higher pressure, but it's the same case and projectile size. Johnny DeLoach Jr.
