Did your primer come from a white arsenal CCI box or a blue and silver?

Have you cleaned the bolt face and inspected for cracks?

Could you post a pic of what a few of your typical primers-in-the-pocket look like?

That's an Armalite bolt.

How deep are your primer pockets? Those primers look very deep in the loaded rounds, and your chamfer to remove the crimp looks a bit heavy. I'd also agree your primer may not have been seated correctly.

I thought they looked deep to. I have the rcbs pocket uniformer and tried to set it but it looks like it's non adjustable. I'm just deburing the edges after I cut the pockets. I'm also using the lee primer install tool that goes with the press. It has a spring loaded cup that you put the primer in and I thought it would keep it straight, guesss not. I'll watch it more closely.

Most guys use the flat primer seater and seat by feel, LEE will tell you to use the flat primer seater on CCI primers and flatten the primers just a little to set the anvil.

Here's how I do my pockets, resize case or punch out primer with a punch, then chamfer the case mouth first with an RCBS .17-.45 chamfer tool part #09349. Depending on the crimp, staked or ring is the challenge when chamfering them as the staked primer pockets like to bounce the chamfering tool. On the staked pockets I go slow to keep the mouth of the pocket even and to keep the chamfer from bouncing, Once it gets a clean surface I like to remove the stakes from the mouth of the pocket. Don't go nuts and remove ALL of where it's been staked as you'll cut way to much material off, you just want the mouth of the pocket clean.

On the ring type crimps I remove enough material so that you can tell the primer pocket and the mouth are straight or in line with each other. If there's to much material on the side that has the ring hanging over the mouth it will cause problems seating the primer. Same as with the staked primers, if you go nuts and try to remove all of the ring crimp you'll ruin the brass.

Now for cutting the pockets, with a good chamfer the primer pocket uniformer will go into the pocket without to much trouble. The K&M uniformer is tight and if you don't keep it straight it has the tendancy to bind. You can use some Imperial sizing wax or Hornady's Unique as a lube but you'll need to clean the cutter as the shavings will build up on it. I try to keep a little on my finger and just wipe the side of the cutter to keep this from happening. If you own a K&M uniformer you know that you can pre set it for .220, I like to keep my calipers handy and check them from time to time. Most of the time it's easy to tell if the pocket is deep enough as the uniformer will rub on the back of the case.

Power tools such as a drill will make these steps easy but you need to be careful, don't let the drill sit there or as I stated above, you can ruin your brass. Just remember to take it slow, watch what you're doing and you'll have your brass done in no time.

I measured the pocket and it was .218" deep and .311 wide. I'm pretty sure I just got it started sideways a bit and crushed that one side. I did check all the other pieces I preped and there all about .218-.220" and .310-.313 wide
