Primer pocket issue.

[wilderness medic]

Having an issue with my primer pocket. Reloading AE 5.56 brass.


Some of the pockets are not centered. Is this normal and ok?




Also I’m getting a brass shaving lip in a lot of the pockets popping up after priming. I can peel it off fairly easy. Does this mean I have to uniform it or debur? Why is it happening with once fired brass? I don’t see it until after priming. Some of them push the little brass lip off while priming like it’s shaving it

[wilderness medic]

Maybe I’m not properly aligning them hand priming? I noticed if I lightly push the primer in a tad and spin the cartridge it doesn’t seem to happen and it goes in smoother.

If it's the same as the bulk AE/Federal brass I had you need to uniform and bevel the lip. Pissed me off having to do it x3000 but do once, cry once. And then never pick up .223/5.56 range brass ever again because memories of case prep instill primal rage.

[wilderness medic]

Disregard. Found the exact same issue.

I use only LC range brass in my reloads and I've run across your problem. Finally got myself a Lyman case prep center a few months back to speed up the process of chamfering, deburring and cleaning primer pockets.

I found that if the primer pocket cleaning tool gets stuck in the primer pocket so that the case starts spinning, the pocket is not properly swaged. I set those aside and swage them again.

I bevel my brass . Pain in asz but makes handpriming a lot easier. Less Upgefuked primers

Is it typical for the primer pocket to be so far off center? Now that I’m giving it a wiggle it finds its home and seats fine, but man half of these are waaaay not centered.

First of all, those pictures are not big enough to see the off-center-ness you're talking about. Can't even read the headstamp.

Those primer pockets might be crimped, the kind that doesn't look crimped but it is, like I was talking about in your other post.

Hard to tell In those pics. But I suspect those are crimped primer pockets.
Take a close up.

Need a closer pic of what you mean offcenter.

The primer pocket looks centered to me.

Are you referring to the flash hole? Flash holes are frequently off center, ragged, not really 'holes', etc.

Not normally a problem, but one of the signs of primo brass are uniform/smooth flash holes. If you're going for 1 ragged hole accuracy it can make a difference. Pistol calibers I don't even inspect the flash hole.

This site blows for uploading pictures.


No the primer pocket. Its definitely not centered.

Before you take a pic. Lower the MP setting. That way it does not have to be shrunk so small to post the pic.
Or use a camera. It will have lower MP settings.

I don't even bother with crimped brass . They go into brass bucket with the 22lr
All the brass is either tumbled or vibrated then run thru the prep center .
Every case is chaffered [ both my thumb joints are plastic and I / we reprime
by hand ]
I / we buy cartridges about 1000 at at time [ nephews / nieces ] and pick
up range brass . The exception is 25 , 32 and shot shells .
Range brass is mainly to get 25 , 32 and carbine cases .
9 mm , 38 , 45 , 308 and 223 / 556 we have plenty , but now I / we are reloading
from 500 to 800 at a time .
I only use Hodgdon ball powder [ varget is exception until gone ] and mainly
CCI 250 and 350 primers .
250 and 350 primers are magnum primers and seem to run cleaner than normal
primers [200 and 300 ] . This came about on last shortage .
The magnum primers fire a little hotter / longer and are a little stronger brass .
I would recommend getting a couple of reloading books and read them . Also do
a search on web

Oh the famous primer pockets. Crimp, centering etc. I believe on midway site, I got a go-no & go primer pocket check. Has two sides, one should go the other shouldn't. The one side says you got the crimp out, the no go side is larger and let's you know the socket size is too large. I have (forget brand) shell pocket machine. One removes crimp, the other cleans the pocket another uniforms it. If the no go fits means I worked the pocket too much and it's too large. The small side ( go side) tells me I got the crimp out and it's good to go. I put blue on the go side to check for crimped brass.
