Speaking of brass, I bet I can grab a Winchester, Tikka, Weatherby/Howa, Ruger and ALL will feed all major ammo fine.

There are some issues going on........

I had a local gunsmith long ago when I was in college tell me my 10/22 was misfiring b/c of ammo, and to use Remington, well perhaps they use softer brass, but that was NOT the issue, it was a bushing and recoil spring assembly that needed replacing. All he did was clean it.....and it continued it's problem till Ruger sent me the new part which I installed.

ANY decent firearm should function/feed/fire/extract/eject most all decent made SAAMI spec ammo, IME.

And I caught major flack for concern over Shaw barrel quality...

I hope the owners get a properly working rifle and their money's worth. The platform looks to hold promise, but will only do so if it delivers, and quality control will determine.
