Improving primer jams

v35v35 Member Posts: 12,710 ✭✭✭
I used a primer pocket decrimper on 100% of my 9mm and 45ACP cases today.
Results were no more jams or crushed primers from a lack of radius at the entrance to the pockets.
Some brands like WCC and S&B had little or no radius.
There were also some WW2 Canadian in the mix that really needed it.
I believe it faster and surer than inspection.

    A sharp clip blade knife will cut a fast beautiful taper. What tool are you using? The nice thing about flash hole de-burring, chamfering/cutting out the crimp is you only need to do it once.

    Too easy; I use the chamfering/deburring tool on both ends of the brass.

    Both of the above methods are slower than a resizing button and brass ejector in a heavy press if you need to do a bunch.
    My wrists are aching just thinking about it.

    No aching wrist when you chuck the tool up in a drill. The only pockets I use my reamer on is military brass and the Hornady primer pocket reamer works easy and fast in a drill.
