Perhaps.  Having had some success with the Hornady 150grFMJBT and boosted WC860 I decided to see what Nosler 168gr BTHPs would do with a similar load.  5.7gr 10B101, 44.5gr WC860 in twice fired BCC brass, with CCI#34 primers.  I had the barrel warm from shooting ten of the 150gr loads before shooting the two 168gr groups pictured. A fellow left me some nice targets out on the 100yd line.  The black was bit smaller than the SR1 that I usually use.  But they only had a couple holes, not in the black, so I figured I'd put some in the black!  Point of impact was up and right, compared to the 150gr load, which was hitting Xs on the SR1.  Top group was fired first, then a single one which impacted about the same though I had adjusted the scope.  A few more clicks down and left, then the five shot group pictured.  I had figured the Noslers would do better than the Hornady's.  Those were long ago purchased bulk bullets.  The boosted 860 load did much better than a lot of combinations with the same bullet that I tried before the match last year.  Recoil was a bit more than the 150s, but no more than the same bullet in my Garand over 49.5gr of IMR 4007.  I closely checked the locking lug, no evidence of cracking.
