I don't know if this applies but I'll throw it in for shits and grins.
I use to dabble into international rifle shooting. The 308 was used back then as the primary 300 Meter Rifle. (Three position).
Don't remember where I read it, but in 300 M ISU shooting it was determined that 2200 fps was the most accurate speed for the 308 using 168 grn SMKs and Hornady Match.
I tried it on my M1A heavy match and it did seem to be more accurate then the standard 2550 fps load, except it wouldn't always work the action. Fine for slow fire, but sucked in rapid fire.
You might go to the CMP site and e-mail Gary Anderson. He was a wiz at 300 Meter ISU, certainly got enough gold metals in ISU, including setting the record for 300 Meter stand which still holds today.
I did ask him about his load, said it doesn't matter as long as he used 168 Hornady's. (All rifles are different, my M1A likes the SMK better then the Hornady's, but I'm not Gary Anderson).
Anyway, try reducing your velocity to 2200 fps and see what happens.
</div></div> I agree:even if I'm not a former 3P, my bigger shooting smiles comes often after "not-full-throttle" reloadings_ Beside that, I think reasonable to place at 200 a black disk of the preferred diam.,triyng to REDUCE the time wasted to focus-and-refocus your eye on a properly focused reticle_I say that because,if your effort to see better-and-better is too much,you forgive that your eyesight REAL clarity after 5 or 6 seconds is gone,and after those 5 sec.you squeeze the trigger following only the last image impressed on the retina and perceived by the brain,but this it's the picture of seconds ago,and in this time you can have moved,expired,inspired,or anything:your position can be slightly changed,but your brain is still on few seconds ago...In this case,STOP_relax,close your eyes,see the grass around you,and try again,not for more than 5sec._ this works for me,and works even more dramatically with anschuetz or L1A1 peep sights_ The black disk on white paper is because if you work for testing the rifle,your mind must be focused on the fundamentals,not on the previous hole:if your rifle/scope/reloads/ are ok and the fundamentals are respected,a tighter group will be the logical consequence_ (I hope, but,like the real WileCoyote, I never stop to try)_Forgive my bad grammar,please_
