It's a decent enough calibre, although many have found it to be a bit too hot of a cartridge, which is why the .40 S&W was created.
It's not safe to do. You won't get proper headspacing (the 10mm casing is significantly longer), and the end result could be disastrous.
Either platform can be larger than the other. The 45 has the larger projectile. Caliber is defined as the diameter in fractions of an inch, so .40 caliber is smaller in diameter than .45 caliber. Caliber can also be defined in the metric system, measured in milimeters. The .40 caliber cartridge is equivalent to 10mm in diameter. As noted, the size of a handgun can vary widely within one caliber, so it is perfectly reasonable to have a smaller handgun crafted in a larger caliber.
S&W Model 16, Colt
A 40mm handgun would fire a bullet the size of a golf ball. No such critter. There IS a .40 caliber handgun (about 10mm). There are dozens of larger caliber handguns than .40 caliber. They include the .41, .44. .45, .455. .460, .475, .500- and several others.
Yes, colt makes a few different versions of the 22 caliber handgun such as the Woodsman, and Challenger.
Assuming you mean a bullet fired from a .22 caliber handgun, the answer is, yes, it can, but it depends on several variables.
mp5, 9mm,10mm, m16,rilfe im not 100% aure A good friend of mine is a Park Ranger, and his department issued handgun is a Sig 220 in .45 caliber. I don't know about long guns.
Its the size of the bullet that the gun is made for. its the caliber that a handgun uses
It should be marked as to caliber on the barrel.
No.
It depends on several factors, but a good rule of thumb is "about a mile."
Probably. It would likely refer to a handgun that fires a .45 caliber ACP, or .45 GAP or an older .45 caliber revolver round.
