That was obviously a problem with THAT particular case.

Over pressure and/or chamber problem had nothing to do with that failure. THAT is also obvious as no other such problems existed.

RIPP - that .223 shoots almost as well as my CZ Hornet Lux with 40gr. at 3,340fps (14.4gr. LG in RP brass - safe only in MODERN Hornets).

Not a fair comparison though, as the CZ is a bolt gun.

Nice group.
