Seat Crimp die adjustment

need directions for the R/crimp set.

Seat a bullet to the correct COL. Back out the seating stem. Then with the round in the fully raised ram, screw the die in by hand, crimping as you go. Can not over crimp this way if brass is all the same length. With a roll crimp, brass length with a variation of more than .005." May produce a bulge on the one with the long trim lengths. Hey RC, that was a hard one to find. Lol. TY to Walkalong for finishing what i started. So i made this. Hope its correct.

Bingo! At least that is how I always did it.

I'll add:

After that you have a completed round with a good crimp. Run it back into the die, run the seater stem back down until it firmly touches the bullet, then run it down about another 1/8 of a turn. Load another round and check OAL. Tweak as needed.

I always keep one round in the die box just encase I need to reset it after cleaning.
