What do these groups mean???

Just wondering if anyone can tell me if these groups mean anything in particular about my gun, my loads, etc. Iíve had all three of these come out of my 338 Edge which Iíve been struggling with.

Thanks.

Well If I was shooting a provin gun and load I would say it's your trigger pull and breathing not knowing anything else about the situation.

300 gr SMK 0.015 off the lands typically yields groups like #1. Jammed into the lands yields groups like number 3 and 0.040" yields groups like number 2.

Loads are either 92 gr of H-1000 or 94 of Retumbo and CCI250's...both have given the same groups. These groups are at 100 yards and are between 0.8 and 1.2 MOA.

Just wondering if my loads are the problem This gun is not shooting well and after 150 rounds is still a copper mine...

Thanks.

I would say, go back to group #1 and move it in and out (probably in since jammed gives you two close and a flier) in .003 to .005 increments until you find the best group and then adjust your load up and down in .3 to .5 grain increments and some where in there you should find THE load.

I would still retest #3, just go back -0.005" and fire off cold shot before firing any groups, on #1 go up another +0.005
