I was reading a book forget what book it said not crimp 45 acp when reloading i going to do it anyway lee reload book said to crimp them so thats what iam going to do. Just like to know if anybody else had heard this. :brow:
most pistol rounds headspace on the case mouth. if you crimp them the round has no place to headspace. most everybody just uses lee final crimp dies to make it to factory spec and skips the hard crimp.
I have heard and read this also. LOL, but I ignored it and crimp using the Lee Factory Crimp die so it will be at factory specs. Found out that when I did not use the Lee FCD a significant portion of my rounds wiuld be oversized according to the case gauge I use. IMHO and experience crimping the 45acp with the FCD is well worth doing.
ahh crimping..lol....I have found in my experiance that with most "production" projectiles it is not neccasarry to add a hard crimp. I have found that with most of my hand cast rounds i need the crimp to help hold the bullet that extra split second to get the best groups. The way i see it you can never have enough reloading stuff. Go ahead and get the crimp die cause sooner or later you might need it and its a PITA to have to stop a good loading session cause you dont have the right tool.....Just my 2 cents.
Use a taper crimp on 45ACP. I think all currently manufactured dies are taper crimp. Use the minimum crimp that will allow the case to enter your gun and hold your bullet in place. It will extend the life of your brass.-D
