I want to reload for a 45 long colt built in about 1959 to 1960. I want to use jacketed bullets and I am not sure to use .451 or .452 diameter bullets. Can someone tell me where I can get the info on this?
Slug your barrel and be sure. Most manuals will give you the proper procedure and I'm sure you can also find this information on the 'net. FYI, I have two Colt's dating to the 50's and both mike out at .452".
