Noone has ever explained it to me. What caliber is a 45/70, 22/45, 30/06. I figure the first number before the "/" is the caliber but what about the second number?
For the most part this is true but there are some execptions.The xx/xx is a black powder cartridge designation the first number is the bullet diameter and the second in the grains of black powder
Diameter of a .45 caliber pistol bullet is around .451 (if jacketed) and .452 (if lead), although some people prefer a .454 lead bullet in some .45 caliber, single action revolvers. Bullets in .45 caliber (for handguns) run from 165 grains to 250 grains, with 230 grains being the "standard" for an auto-loader and 250 grains being the "standard" for a revolver. Some folks will use 300 grain bullets for hot revolver loads.Eric F said:the 45-70 is a .457 to .459 depending on the barrel IIRC I am not certian of the 45 pistol caliber sizes....
.45/70 is a cartridge, not a bullet. A cartridge is a package containing the four components necessary to shoot -- case, powder, primer and bullet.OK, I get the diameter/grains of bp idea but could I use a 45/70 bullet in a SAA or is that round specific to a certain gun?

The xx/xx is a black powder cartridge designation the first number is the bullet diameter and the second in the grains of black powder. a 45/70 uses a .45 caliber bullet over 70 grains of BP.
30-06 is not designated with a slash but a hyphen meaning 30 caliber designed in 1906---SMITH357
