Re: Crimped primer pocket
I just did a bunch of 9mm brass w/crimped primers. I use a 60 degree high speed steel countersink. The one I have has a hex shaft and fits in my drill/screwdriver, and I did mebbe 100 in about 15 minutes or less. My countersink cost less than $10.00 and I've been using it for several years to knock out the crimp on military primer pockets...
