I want to try loading a .38 Special with a Lee 1252R (90309) bullet sized to .358". As cast bullets measure just over .358"; when szing they are just barely touched by the sizing die. This bullet is intended for the 9mm Luger. The "issue" is that it has no crimping groove. I can use either a TC crimper or the roll crimper, which is built into the Lyman Seater die. Will use 3.5 of Bullseye or AA No.2 . I am trying to duplicate Winchesters factory .38 Spl ammo that uses a 130 RN bullet. I ask anyone who has tried this what has worked best for them as pertains to crimping. I use ACWW as my bullet alloy.
