I've tried them all so far. The "Lee" seems to work the best, but, the handles are made of cheap cast metal and they seem to break about every 1000 or so primers. "Natchez" sells replacement parts for around $2.00 each and I buy 5 at a time so when one breaks, I've got a back up. When there are enough broken one's, I send them back to Lee and they replace. The extra work pays off when every round goes bang!! Also helps your grip strength.
