bentz chaimbers will shoot most standard ammo, thats why they were invented, they are a comprimise between standard and match. i have had three barrels, (or guns)with bentz chambers. i never tryed stingers, but the only ammo i had any trouble with was the tighter match ammo. it becomes less of an issue when your shooting a single shot, and more of a problem with a bolt or worse with a semi auto.
