Thread: Micrometer Seating Stems - A Primer

I've found the hornady stem to be OK but if you want ultra exact results then you need to faff with everything you can think of. Annealing, brushing out the red oxide and then dusting your projectiles.

I can't stand the crude bolt adjustment you get with an RCBS std seater or worse (the heavy bolt on the lee seater).

I check the first 3 or 4 round with the comparator / calipers to make sure I'm at least .02" off and then I just do 50 in a row after that. Or .1" off the lands if it's my own pc cast projectiles.
