I am getting the most consistent accuracy from that combo, 80gr rl33 .07" off the lands, fed 215m primer. I shot both weights of lrab, berger 140 vld and hybrids, 140 hornady sst, hpbt match, amax, 140 accubonds, 120ttsx. The 127 lrx outshot them all in this barrel.
The thing that I see in the 6.5's is there is not enough bc difference between the heavies, around .61g1 bc and the moderate weights- .5ish g1 bc to make up for the velocity spread. I can drive the 127 to 3550, but a berger vld only 3275 before running into pressure signs. It different in say 338- moderate weight bullets in the .5bc range with a few of the heavies around the .8bc, the bc will more than make up the speed difference.
I also shot most of those bullets into my test box - shredded loose leaf paper soaked in a rubbermade tubby. Even at 200 yards the bergers basically turned to shrapnel in the first 3" with no penetration past the 6" mark. Once out to 500 they worked as expected. The bonded or copper bullets performed, the lrab expanded right to the base at 100 yards, but stayed in one piece. The sst/amax were very similar to the vld's - basically schrapnel with very little penetration. As this is a hunting rifle, and for its purpose I won't be carrying two loads, the Barnes was the smart choice. Although I did shoot an elk with the 140 accubond last fall and it worked very well.
