1:9 twist is better for all but the heaviest or longest 5.56 bullets. USMC figured that out back in the 1980's, don't know why some still think higher twist rates are needed when they'll never shoot anything heavier than M855.
I wouldn't trust MK 262 Mod 1 out of a 1:9 which would be the only reason I would lean 1:8. My favorite ammo I wished I could afford to shoot it. It's the best I've ever shot out of my 1:8 twist Faxon 18" Gunner. I struggle to hit the 4" gong at 200 yards with most everything else (A mix of Wolf Gold, Barnul green steel, or AE M855). When I do hit the gong it will be on the perimeter usually at a rate of about 50-60%. I can bang a 2-3" circle on the 4" gong all day with the MK262M1 @ 200 yards. So personally I would prefer a 1:8 on the very rare occasion I hit the 200+ yard range. But for the 100 yard range and for hitting silhouettes instead of 4" gongs it's all 55/62gr and I wouldn't have a problem at all with 1:9.

I've had no issues with them in my 1:9 twist rifle. I've loaded dozens of 75gr and 77gr loads and while the size and location of groups would change a little, none showed any signs of being under-stabilized and most chronographed above published specs. Mk 262 is just a canellured 77gr SMK which at 0.981" are considerably shorter than M856.
