Thread: barnaul 62gr fmj v PMC 55gr FMJ v PMC 77gr SMK

Those PMC 55s are all over the place for velocity.. That's a 200FPS spread

Which perhaps explains a few of the results I've been getting with them.

Same here, the group above was pretty good but Ive had some way worse groups and I was assuming it was me (maybe it is, LOL). Also the "28xx" series was one box the "27xx" was another box, but the "27xx" was a clean gun in the cooler morning while the "28xx" was 150+ rounds later in the warm afternoon but 100fps seems a lot of gain just for a few degrees air temp and an AR that is a bit dirty?
