Was putting in some primers In my 7mm rem mag and was surprised with how easy they went in. I can get them to fall out with a small tap on the counter. I double checked I was using magnum large rifle primers so that's not the cause. Assuming I should just use these cases for scrap metal and buy new brass? Any ideas of the cause?
Also would I be able to punch out the primers and reuse them without damaging the primers?
If the primers are that loose, the brass is beyond it's useful life and should be tossed. I have been successful at removing new primers, but be careful and go slow...if your pockets are that loose they should come out easily.
I never disguard brass, until I can see daylight though it, so here you go, I figure it will pay for itself after only 50 pcs of brass, that I other wised would have chucked, my good old stand by trick is to use a drop of super glue to hold the primer in one tube fixes hundreds of cases, all it takes is a drop, that fix has been use for years with the benchrest guys.

Dean you are much braver than I am. I don't trust my eyes and face to super glue. If it does not take good pressure to insert a primer it goes in the trash. Your eyesight is not worth a cheap brass case.Quote:

hahahaha oh my, only Dean!
He's right though, the superglue only hold it in place, once fired the primer should expand to fill the pocket unless it's super loose....that being said, my questionable brass hits the recycle bucket for the next crazy rise in brass prices.
Looks like I've got a simple solution for the brass I have with loose primers for now. Will probably turn them into scrap metal after firing them and move on to new brass. I've got enough spare change to get new brass so it's not worth the hassle to keep gluing them!
The swage tool dean posted works great and is worth the money. The reason your primer pockets are loose is because you are probably running a fairly hot load. Back off a half grain or so or your going to have the same problem with new brass.

OK, I apologize ahead of time Dean if this is a stupid question. So after the super glue trick, and shot. Is the brass then headed to the recycle bucket because you cant get the glued in primer out? Just don't see them coming out too easily then.

snipe, the glued primers will come right out with your decapping die. They are broken loose during firing and pushed back against the bolt face to take up the .002-.003 depth below the base they should be seated.

Anyone else and I might be surprised. The way you load 'em I'm surprised they stay together at all.
OP - You tried using CCI primers? I like Fed brass which usually lets Win primers fall out after 4 to 6 firings. CCI primers give me another 5 to 6 firings.
Or, go with Deano's solution and get a tube of Liquid Nail and a caulking gun.
For me chancing a blown primer and a scarred bolt face isnt worth a pc of brass. I hand prime, if it goes in very easily i tap it hard on the bench a few times.
If it comes out or even partially out the case gets chucked. i know guys who do the glue thing for 1 more time. Also a few who use the tool. I'll buy brass.
You can also try Wolf or Tula primers as they tend to be a tad larger.Quote:
