Please help me with my Ruger American .308
Before I sling it into the river.
Can't get it to group. I've tried 165 grn Hornady Interlocked, 165grn Fusions, 150grn Hornady SST. Using a lead sled trying to get 100yd groups - the worst are the Interlocked; groups are about 5". The best are the SST's; grouping at about 3" - which isn't great. Letting the barrel cool between groups. I've cleaned it and gone back out, no difference. I think what I've got is something beyond just shooting an ammo the gun likes. I realize I'm not shooting the high-end stuff, but it's the bargin bin either. And I don't think that ANY ammo should be grouping at near 6" @ 100yds out of a well functioning rifle. I just put a different scope on it just to eliminate the optics as a possible problem, but I'm very doubtful that's it. Everything I read and hear about the RAR is it's an accurate rifle. That certainly hasn't been my experience. I'm open to any suggestions. Very frustrating.
