I just bought some Colt 45 caliber boolits off of a relative and can't figure out exactly what I have here.
It looks to be a Lyman #452424 or RCBS #452-270-SAA. He has them listed as 260gr and they weigh out at about 264gr.
The boolit height is 0.795 inches.
The problem I am having is getting the crimp in the groove and having the OAL within specs. The best I can do is about 1.660 OAL. The case length is under max.
Should I just trim the cases back to fit? Any thoughts?
