Without reservation the biggest surprise ive received in while. I am impressed, excellent quality. Out performs all rcbs priming tools i have, including the bench primer. Heavy duty construction through out. No plastic observed with the exception of the primer tray which is also well thought out. A lot less effort required to seat a primer. Less travel of the handle to seat primers with a very positive stop mechanism. Adjustable seating depth. Simple and easy shell holder change out. No disassembley required. Shell holders are included with the tool. Most popular calibers are covered. The shell holders are marked. Each has a marked storage position inside the fitted case. Yes, a case. Put one of these bad boy's in your hand and smile. They work really well. It takes approx 20-30 seconds to change out a shell holder and primer size. If you need a new hand priming tool, or even if you dont, get yourself one of these.
