Crimped primers?
 

What all has to be done when trying to reload brass with crimped primers

Primer pocket reamer. Lyman, RCBS, etc.

I chuck a case neck chamfering tool in the drill press. Easiest way i've found.

Both methods above work well. The "sheepsfoot" blade on your pocket knife will work to scrape the crimp out. These methods are for a small number of cases.

If you buy MilSurp cases in thousand lots, invest in a Dillon swaging unit. A bit pricey, but a lifetime investment that your grandchildren will appreciate. If you value your time and labor, it's a bargain in the long run.

I got the Lyman handheld, pulled it out of the handle, and chucked it in the dewalt.

The Gracey primer pocket uniformer cuts the crimp as well as uniforms the pocket, each unit is cartridge specific, a little pricey, but great for large volumes of brass.

I use the RCBS trim mate. Not to expensive and it has 5 stations I decrimp, inside and outside neck chamfer, clean the primer pocket and run a neck brush. Great for large batches of brass.

Sounds like a good economical solution.:)
