I was thinking to cut .450 nitro brass down to 73mm...the ram them up into a 450/400 3¼" die. It seems that the .450/400 Purdy and the 450/400 3¼" express has the body only the 3¼" case has lo ger neck. I have looked through gun and cartridgebooks I have and no 450/400 2 7/8" shows up with case specs. George Hoyem books has the cartridge shown but skips the case specs.(thats was actually the only case where case specs wasnt there.) |
