.355.
Yes, a bullet must be the same diameter as the barrel (unless it is a shotgun).
.223
.284
The bore of a gun relates to the diameter of the hole in the barrel - and in turn the diameter of the bullet the gun can fire.
Probably. It depends mostly on the composition of the bullet, lead bullets are designed to be molded as they pass down the barrel ... that's how you get rifling.
between about 1000 FPS and 1800 FPS, depending on the cartridge specifications and the length of the barrel is it fired from.
either .223 or .224. Have the barrel slugged.
The bore is the inside of the barrel- that is, the hole that the bullet is fired through. The diameter of the bore is measuring how wide the bore is from one side to another.
The 9mm means that the bore is 9mm inside diameter . The bullet will be roughly 9mm or a little more in diameter. The 45 means basically the same, the bore of the barrel is .45 caliber. but the bullet will be anywhere from .451 to .452 in diameter depending on manufacture and on type of metal the bullet is made out of. So basically yes.
The diameter of the inside of the barrel in hundredths of an inch. A .45 caliber (check your spelling) fires a bullet 45/100ths of an inch in diameter.
The size of a given bullet is determined by its diameter, and its weight. The size must match the size of the barrel it will be fired from, and heavier bullets will be longer. With cast lead bullets, after casting they are pushed through a machine called a die. This squeezes the bullet down to a precise diameter- this is called SIZING.
The chambers of the sample HW5 which I inspected were bored the same diameter (cartridge case diameter) straight through. Chambers of good quality revolvers (e.g. Smith & Wesson and Colt) are reduced to bullet diameter at the front end (barrel end) of the cylinder to guide the bullet squarely into the barrel. With the HW5, the bullet must jump from the neck of the cartridge case to the barrel with no guidance to ensure that it enters the barrel perfectly in line with the barrel axis. This is not conducive to good accuracy. Bored-straight-thru chambers were common back in the days of outside-lubricated bullets having the same diameter as the cartridge case (like the .22 rimfire) but the 32 S&W is an inside-lubricated cartridge design and should have reduced-diameter chamber throats.
