-----a 38 cal pistol cartridge is actually 35 cal
-----44 colt is a 42 cal-----as is the 44 mag-----
-----bullet for the 44 is 429 diam.---if the barrel was 44 cal. the bullet would bounce through it-----
I think the .38-40 WCF is a .401 Cal. or 10MM. The .44-40 WCF is .429 or .430 the same as the modern .44 Cal. American Handguns.
Ouch! My head!
Looks like calibers are really "nominal". :rotf:
