Primer pockets too small...

Bought a new bag of Winchester 30-06 brass and sized up about 20 of them for loading. Went to prime them...primer would not go in the first one...stuck almost half way out of the pocket. Thought it may be press priming tool so I broke out the hand priming tool. Same thing happened on the second one. Using Winchester WLR primers.

Anyone ever have this happen to them? What is the cure to this ill I'm having?

Thanks in advance!

Bad lot of brass maybe?

Odd thing with new brass. Believe I would take it back. Have you "spec'ed" the pockets (and those primers). You can always get a large pocket reamer tool and open them a bit.

But that's a PITA.

Measure pocket depth with a mike and see if they are correct. If so, a bit of a chamfer on the edges might help seat better.

RCBS primer pocket swager would make quick work out of them but you shouldn't need to.

I use the swager to get rid of the military crimps on .223 brass and the crimp on some .45 ACP small primer brass.

Sometimes sending back the brass is more hassle than it's worth which is why I recommend the swager.

besides old age I have a problem with a lot of new Winchester 30 carbine brass--primer pockets are very tight---so I use a modified RCBS auto prime tool:

It gets the job done.-----------:)

First time priming new brass? If so, just push harder. New brass is ALWAYS harder to prime, once fired brass has the primer pocket expanded a bit. Just remember, you can't fire a primer with slow steady pressure. Lean on the priming tool, push 'em in.

Like snuffy wrote, just push harder. New brass is the right size.

I had the same problem back in March, bought 1K Wolf large pistol primers and had one heck of a bad time trying to seat them deep enough in Winchester AND Remington once fired .45 Colt (by me) cases. Wound up seating them on the press, usuall use the Lee hand (thumb) prmer tool.

Didn't like the look of the primer after so much pressure was used to seat them, they looked kind of dimpled, any way they shot ok.

So now I had about 400 Wolf LP left and didn't want to waste or give up on them.

I used my Lyman large primer pocket crimp remover - pocket uniformer, chucked it up in my drill and ran about 100 cases each of Rem and Win. the Wolf primers slid in like they had grease on them, you coul feel them bottom out with just thumb pressure.

Try that on your '06 brass.
