The Puckle Gun had a bore of 1.25 inches, or 32 millimetres.
It has been made in several calibers, but the original was .45 ACP
They are two different calibers.
Did you want to know what calibers were used in machine guns or perhaps what cartridges are for machine guns only.
This was made in 3 calibers- 9mm Parabellum, 10mm Auto, and .40 S&W.
The question is a little difficult to answer as asked. MANY guns are centerfire. There are a number of calibers available that are rimfire, but the most common currently is a .22 or .17 family of cartridges. Almost all current larger calibers are centerfire.
No. Standard ammunition in the correct caliber for the gun. However, ONE of those calibers is the .357 SIG auto, and other .357 cartridges do not interchange with that.
Depends on how much money you have. Springfield Armory makes an excellent and very safe pistol called the XD. Available in 9mm, .357Sig, .40 and .45 calibers. Your best bet is to go to a local gun shop that has a range that rents guns. Try out different models and calibers until you find one you like. Join a local gun club and ask the members questions.
