I must be getting old, but here is the problem. I have loaded this caliber in the past. I cut down some 44 cases to the correct length, sized the bullet to .427 per the barrel casting. seated the bullet with a 45 acp die and then I went to crimp the case. Here is where I think I am loosing it, my notes say to crimp using a 303B crimp die. OK, how is a long reach bottle neck die gonna reach a case about .898 in length?? When I look at the ammo I had previously made I can see the marks of a nice tapered crimp on the case, giving me a nice smooth transition.
Thinking I had lost it I decided to make a crimping tool. Bought a 44 mag crimp by Lee, shortened the outer case after I drove out the crimping portion. Now I had to cut the crimping portion shorter than the base holding the fingers so I reinserted that portion and epoxied the insert to the housing as if I didn't the fingers would fall out. Got it done this morning and did the final cut to case length. Works pretty good, but it doesn't give me the nice crimp I was getting with I haven't figure out with what I did it with. So how is anyone who is rolling their own for this caliber doing the final crimp???
Pulled out the revolver and tried the ammo with my new crimping tool. It didn't seat all the way. Pulled out the .303 dies and looked at the crimping die in a different way, there is a nice taper going into the die, tried my ammo that wouldn't fit pushed it in till it would go any further and tried that in the revolver, fell right in and seated perfectly.
