Testing some 300bo today and got a few jams I’d like opinion on. Empty case somehow got stuck up in the hole on the bolt carrier op handle. Can’t say I’ve had this kind that I remember. Is there an obvious cause y’all can see from here?
These were lil’gun loads with 150gr hitek coated sharp point type pills. I’m not sure how the base of the cartridge could jump out of the bolt face and up like that. Tried two mags.
