Sorry, my mistake, it is .375. I have never loaded for one. And yes Chantecler the correct term is cartridge. Caliber has been bastardized to describe a cartridge. First I would ask about a particular model of firearm, then I would ask if it was available in a particular cartridge. Trailer is correct in his description. Tom.
HEAD, while I was a little bit aggravated about this caliber/cartridge thing to begin with, I have thought it over, and you guys are correct, caliber describes the diameter of the bullet that is being fired in a particular cartridge.
