Can anyone tell me the bore diameters of 20ga, 12ga, and 10ga? I'm just curious.
Also, how does the velocity of a 20 or 12 gauge slug compare to a typical big-bore rifle cartridge, say, .45-70, out of an equally lengthed barrel? I'm guessing the .45-70 is quite a bit faster, but I'm not sure how much.
