I am hoping you guys can help me with this. I shot a 4 shot 1" group today out of my 7RM with 62 grains of IMR4831 pushing a Berger VLD 168gr. bullet. So I pushed it out to 500 yards and shot very erradic like about 12" group. Theoretically, if a gun shoots MOA at 100 shouldn't you expect that (barring shooter's error) that gunn with the same load would shot 1 MOA at all distances? Or can a bullet loose it's accuracy as the distance increases? Also, with this same set up I had shot a 5.5" group at 700 yards right after I first bought this gun used. Someone told me I should clean it good, so I used Birchwood Casey's Foaming Bore Scrubber. I haven't been able to get it to shoot tight groups since. Before I was shooting 1/2" groups at 100 yards. Any suggestions? Should I just chalk it up to shooter's error and keep practicing (I was using a bench rest), or should I try to modify something in my load, bullet selection, COAL?
