My 8.5 twist 6.5-284 did so well with 140 VLD Hunting, I've not used much else. With RL-17 at 3K fps, it does well, chest shooting WT's, puts them down quickly without busting up shoulders, messing up a lot of meat.

My 6.5x55 really likes 139 and 155 Scenars. I haven't used either one on critters. Hope you're wrong about the 139, if not, I may use 155's in that gun.
