Different brands of WSM brass in an AR-10/LR308

[Earnhardt]

Has anyone used Lapua 300 WSM brass in an AR yet?

How did it hold up at the .200" line? Quite a bit of expansion, or no?

Since the WSM brass is .555", did it need to be re-sized by a .550" RUM or Nosler sizing die, to get the .200" line down so it could be chambered?
My Nosler and Norma brass does need to be sized down with a .550" RUM die.....the ADG I don't use in an AR anymore.

I've actually had problems with ADG WSM brass in an AR. It didn't want to size down very well, and it had shavings/flakes in the chamber area, that ultimately caused jams.

My best luck has been with Nosler believe it or not... no problem sizing down with a RUM die, and no shavings...with Norma being second

But before I drop the $ on Lapua brass, I want to see if anyone has had good luck with it in a WSM AR.

Thanks

I havent used lapua but had issues with winchester and hornady both. Starline seems to be fine. Resizes with no issues

Do you think ADG 6.8 western brass would cause same issues. Thinking about doing an AR in this chamber

I didn’t realize ADG made 6.8 Western brass now…

I’d still have the 6.8 Western barrel chambered, but maybe only buy 50 pieces of the ADG brass at first. Just in case it does the same thing with my 358 WSM ADG brass, that was necked up.

I think the 6.8 Western would be a great AR round!

Trying to find that brass has been difficult lately…if anyone knows?

Is it easy to modify 270 WSM brass, into 6.8 Western brass?
