Starting My Grendel Journey

[KC_Joe]

Currently waiting on delivery of an 18" upper, and in the meantime I've ordered ammo, bullets, dies, etc. Frontier ammo arrived today, and.the primers are crimped......internet tells me a chamfer/deburr tool is the easiest way to deal with this when reloading if I don't have the swager, but wanted to ask if this was a good idea? I also ordered 100 pieces of new brass, so not a huge issue, but since I've never dealt with crimped primers, I feel I should educate myself.

Thanks!

I wouldn't say using a chamfer tool is the easiest way to remove the primer crimp but it is the most convenient way to do it if you already have the tool. I used a chamfer tool when I first started reloading 5.56 & 7.62 NATO brass for three gun matches. But, having had carpal tunnel syndrome in the past, it got pretty tedious quickly. I got swaging tools for crimped brass & haven't looked back.

Just get a small primer pocket reamer like Lyman #7777784 for $12 from Midway. Take the reamer from the handle and mount in a drill or drill press. Easy one time operation. A regular chamfer tool will damage your brass.
I'm sure surprised to hear commercial, non-military, ammo is crimped.

I'm sure surprised to hear commercial, non-military, ammo is crimped.

Frontier (Hornady) ammo is assembled in the Lake City ammo plant. That would explain the crimped primers.

Thanks for the info.....much appreciated.

I have the Lyman small and large primer pocket reamers. These are very handy and inexpensive. Not the best for doing hundreds of cases but not bad for fifty cases or less.

For $12, definitely gonna put one of these on my bench.

I agree with the others on the primer pocket reamer and drill method, do it a little at a time and it's well worth it IMO, I have picked up a lot of range brass over the years, 5.56 and 223rem that have the primer pocket crimps, I used a swager for a while, PITA!! It's just easier for me to reem them out, even if its just 30 0r so cases at a time! and never have to worry about it again!
