I have put both cast bullets and 00 buck through my 300blk barrel in attempt at slugging. Not sure if cast bullets can be used, but thought I would try! I get same exact results as when using pure lead balls deformed and pushed through.
Several slugs fed from both ends are measuring .3045 max I know its not my calipers because I verified them on feeler gauges and I have slugged my pistols and other .30 barrels and #'s come out as expected for the various barrels an reputations.
I know its 5 groove\land but I am rotating slug in calipers to get a max measurement.
8.25" 300blk upper from Hardened Arms. Don't want to approach them about an out of spec barrel if I'm really the problem
