I think for a stock factory rifle in a hunting class model 5 shot MOA groups are few and far between. There are alot of rifles that will shoot 3 shot MOA groups but 5 is a different story. I handload for all of my guns which in hunting weight rifles not varmint rigs consist of a 280, 25-06, & 257 Roberts. The 280 has been rebarreled with a cheap Douglas but it will group 120 & 140 gr. Bt's under 3/4" for 5 shots. The other two are factory stock except for lightening the triggers. Both will group under and inch with 115 gr BT's for 3 shots, but going to 5 opens the groups to over an inch. All the rifles are fed handloads and not factory so I don't know what they will do with even premium factory stuff.
I agree with you SP. My A-Bolt composite stalker in 25-06 has a 22" barrel, so it's certainly qualifies as a hunting rifle. With 100 gr. Nosler ballistic tips and Hodgedon 450 ball powder I can often keep 3 under an inch at 100 yds. But keeping all 5 in is tough. I think it's because if I get the first 3, my heart rate goes up in anticipation.
