Have to agree with you on the USMC stuff. Bought a couple of thousand loaded rounds in the bulk packs, in 223 50 grain HP to shoot gophers and make into brass. They were on a big sale, and about half to 2/3rds the price of virgin brass. Best they would do is 6 inches at 100 yards. Pulled bullets out of ten of them, was over 10 grains differnece in the weight of the bullets. Pulled a bunch more, same result. Reloaded those same rounds with 40 grain blitzkings and 50 grain SPSXs and they cloverleaf at 200 yards. Brass, powder and primers are fine, but the bullets they were loaded with were crap. Must have been designed for rapid fire plinking in ARs or mini 14s.
Did the same with the rest by replacing them with Blitzkings. I also sorted the pulled bullets into .5 grain lots. The pulled bullets, reloaded in matched groups shoot okay, but this didn't turn out to be quite as cheap or work free shooting as I had counted on.
: Still, ended up with a pile of good brass at the end of it.
