I run wally world thru my old Colt hammerless, not bad, not great either. May have to check out Prvi.
I paid $12.99 for a box from www.discountammosales.com -- which for .25 is pretty cheap.
Prvi does runs of .303 Savage brass every year. THAT is a tough to find casing.
The prvi 8mm Kurtz wouldn't cycle the stg44 I saw.
