I'm shooting 140 grain Partitions in several 1 in 9" ROT Remington 260 and 6.5-284 barrels with MOA+/- accuracy. My 20" 7 MS parts gun shoots them into better than MOA groups, while my 24" 260 700 and 24" 6.5-284 7 do no worse then 1.5+/- MOA and the others fall somewhere in between. The 120 grain BTs and 129 grain SpirePoints and SSTs usually shoot the best groups, but no bullets in the 95 to 140 grain range shoots worse then 1.5+/- MOA in the 7 260s and 2 6.5-284s that I shoot on a regular basis.
