SST's would be way down on my list, maybe off the paper...
If I couldn't get NPT's to group, I'd try NAB's. If not satisfied, then mono's, E-Tip, TTSX, GMX. Barnes accuracy load with 150 gr. TTSX is 46.3 Varget at 2,910 fps.
Scenarshooter likes the 155gr. Scenar in .308. He has photo evidence, a bunch of dead critters...
