Having Major Issues Properly Seating .223 Primers in Brass

Either way. What is being described is the primer not wanting to fully seat. At that point your way past the crimp issues.

HI Shadow. That RCBS can get stuck, what I do is barely spray it with Hornady ONE SHOT lube every 5-10 cases, then its smooth. The main thing with it is having a sturdy bench that doesn't flex or move, then its a lot easier.

I tried case lube, it helped a little. But applying it every 10rnds just made it more work.

I don't have a dedicated reloading bench. My press is mounted to a piece of wood and I use wood working clamp to mount to my kitchen table. Works fine for 99% of my needs. Maybe some day I'll have a dedicated reloading area. But for now it's working.

Either way, cutting the crimp out is quick and easy.

This is the sort of VLD chamfering tool I suggested. Sinclair makes a carbide one.

I suggest finding one you can hold in your hand and take a sample of decapped brass with you just to verify the tip diameter will enter the pocket and cut.

Will work, but I prefer the rcbs tool. No worrying about removing too much material. Just push it in till it bottoms out.

I've had this issue with NATO spec brass before , with both 5.56 and 9mm . For me it had nothing to do with the crimp , it was simply the pocket was not deep enough . I could get them to seat barely flush but it was hard to get there and they were pretty much flattened . I was basically crushing them into place .

When I say crushing I mean it , these are not them but an example of what my gorilla hands can do lol . Smashing the 5.56 primers to flush were not impossible but did take a bit more effort then I thought safe .



Luckily I'm a reloading tool snob and had primer pocket uniformers which did the job . I cut the primer pockets deeper by about another .003 and the primers seated just fine after that with out the flattening .

With nearly all of the rejects in the foreground, the primer was flipped .
You were trying to put the primer in sideways.

I suggest re-evaluating root cause,conclusions,and remedies. Perhaps your auto primer feed needs adjustment. Or you primer punch and cup. Primer pocket to priming punch/cup alignment,etc.

I do not doubt using the pocket uniformer can be good practice. I don't think it would solve the specific problem you show.

HiBC,

I think you missed the first sentence in his second paragraph where he explains those are not the cases he is talking about; just an example of how hard he can squeeze a priming tool handle.

Unclenick : OK,I missed that Thanks!
