I don't think the difference in accuracy between a, say, 60 or 69 Sierra over a 77 is useful. Even they are 1/4 minute better, what are you gonna do at <=200 that couldn't be done with the 77? Further out, the 77 beats them in the wind.
I use light bullets up close not so much because they are more accurate, but because they cut down on recoil.
Those Criterion's are very nice barrels. I sighted one in with 52s and got about a 1/4" group for 3 @ 100.
Oh so many times I've shot the infamous 1/4" group for 3 shots. With any bullet weight in any rifle, just about every time I go to the range.. I'm not going to walk down to the target and take a picture of it every fn time though. I'd be worn out.. 10 shot groups are also highly overrated, but we can all talk about how our guns shoot sub moa for them though.
