I use the Hornady hand primer. Uses the same shell holder as the press, and, after 3 years and probably8 or 9,000 rds, still feels tight. Had to modify it a little when I first got it. My Redding shellholders have a knurling around the outside edge, and didn't want to slip into the body of the primer. So I took my Dremel, and opened up the inside of the primer body. If you figure that you don't have to buy the special shell holders that are required for the Lee, price isn't much different. But, a much stronger unit. gypsyman
