Well I just got my new CZ 550 in 375H&H. Took it out to shoot this weekend and was having feed issues. It was always the last round from the mag. It wouldn't jump from the mag and would hang the case shoulder at the corner of the feed ramp. I had read that some people had issues with the CZ feeding I guess I fall into this unlucky category. FYI - the ammo was factory green box Remington. 270 gr. Any suggestions would be appreciated.
