This thread is a lesson in the fact that you get what you pay for.

I recently ordered 250 pcs of processed once fired mixed headstamp brass for my 223 CZ bolt gun. The thought was to have a bunch of cheap brass to load Midway factory second bullets in for cheap ammo to use for positional shooting practice.

I wound up with over a 100 Federal, around 50 Lake City, and the rest anything under the sun. The brass looks serviceable except.......

Both Federal and LC have way looser primer pockets than the Nosler brass I load for precision ammo for this rifle, even being once fired. I think most will hold a primer this time around. I read online from some sources that the Federal is junk, some say load it once, some say if you can bang the case on the bench after priming and the primer doesn't move it's ok.

So what is too loose to load? And what are the dangers with a bolt gun?

If I need to just junk the lot it will just be a $60 lesson. I found out too late that even though Starline is backordered almost everywhere, you can order factory direct from them and within a couple months have your brass, for just slightly more cost than these once fired. So I have some coming sometime in Sept. Needless to say, this will probably end my expermentation with buying mixed headstamp range brass...........

Or I could have just bought 100 pcs of Lapua and have more total firings than this lot of 250, probably...........

My appreciation for my Lapua SRP brass for my 6.5 Creedmoor has increased significantly.

Once they are super loose I mark the case with an x and toss them after I do their final firing.

some one like maybe Hart used to sell a tool sort of like the trick describer above.

a post stood up about 4 inches and the case was dropped of the post and a tool that fit into the primer pocket was struck with a hammer to tighten pockets with about the same result as the trick described.

Good stuff.

I actually shot a bunch of the Lake City rounds the other day. I tapped every one that seemed loose on the bench and didn't have any come out. No leakage around the primer on any that I saw when I shot them. I'm loading them fairly mild. 23.9 gr of Varget behind a 68 gr BTHP.

I just threw out a dozen cases that I primed and there was "no resistance" when seating primers. They have been loaded 6-8 times so I think they lived their life!

The "no resistance" thing is what I look for, I hand prime so its pretty easy to feel when one is "different" than all the others. The times I have shot those , each time was obvious it was bad, not very loud, very little recoil, pulling the bolt and looing down the barrel I can always see lots of unburnt powder.

Never had one stick in the barrel though.

“Once fired” brass is usually only reliable to just that if you are the person that fired it once.

If the primer stays in, it’ll be ok for at least another firing in a bolt gun. Definitely needs to have some resistance upon seating if to be used in an auto loader.

I’d check any used brass for signs of impending case head separation, but then again I only trust once fired brass from people I personally know to only use factory loads.

Side tracking here.. A guy used to be able to get once fired LC, deprimed, and cleaned off of Military ranges for $100 per 1000. I have used these in my ARs without ever having primer pocket issues. I had so much of it I doubt any went more than 3 firings though. After a quick search it seems most places are just range pickup so you don't know what you're getting.. would be nice to find the military LC brass hookup again.
