SELLING Lapua 308 Small Primer Brass $75 + shipping

I have 93 Lapua 308 small primer brass. 8 of them are once fired and 85 are virgin. They have been necked down to .224 and the necks turned down to 12 thou.

They can easily be sized back up to 308. I had issues with them piercing primers in my gun and had to go back to large primer brass.

Which primer did you use?
CCI 400. I’m thinking the regular primers along with having a lower case capacity fill percentage (I think it’s at 79-80%) caused some sort of funky pressure spike, or something weird like that. I have so much brass for this particular rifle that it wasn’t worth experimenting with. I just went back to plain’ol large primers.
 
What is the cartridge called using this brass the way it is? 22-308?

A 22-243. Usually you’d use 243 brass because it’s just a 308 necked down to a 6mm and that’s one less step to take necking the 6mm down to .224, but I was wanting to use small primer and I wasn’t able to find any small primer 243, so I had to settle for the 308.

Holey moley. And to think the .243 is hard on throats...
 
I bet a Rem 7.5 or CCI 450/BR4 would help a lot with the piercing issues. 400s arent meant for that kind of pressure. Also, if you're bolt/firing pin isn't bushed, that would also help a lot. I noticed on the primers it didn't pierce, they look to be cratered really bad.

Only reason I say those 2 things is because I had the same issues with my R700 223 Wylde I had built last year. Started with CCI 400s and a non bushed bolt/firing pin. Was piercing primers on middle loads. Switched to Rem 7.5s and got my bolt/firing pin bushed as recommended by the guys on here, and I haven't had a single issue since. Shooting 75s at 3K now, so fairly warm loads from a 28" barrel. Nice round primers, no cratering, and no piercing.

Well I have a bunch of 450’s and BR4s so I guess it wouldn’t hurt to give it a try.
