There is about a $300 add on to the primal rights unit that can be purchased. Another manufacturer. This will allow you to seat primers by a dial indicator. This seats off bottom of primer pocket. No need to measure primer height. Seating by varied crush can be achieved. While the above referenced unit works, it is slow in comparison. All other primer seaters, ugly base cps and rcbs with hollands upgrade seats by coming to a hardtop. Absolutely no difference. Rim thickness and primer variation are the 2 issues with a hardstop device. They simply won't work. You have 2 choices..the least expensive being the above reference unit K&M. The other is the F Class products upgrade for the primal rights unit. While most rims are close, 10 out of 50 pcs of brass will be .004 to .005 off 1 way or other.It's a fine piece of machinery and really can prime a lot fast. Really easy on the hands.
1. It does not take into account primer thickness variation
2. It does not take into account rim thickness variation.
The only one that I know if that does this is from k&m.
Does it matter? Well that's for you to decide.
