My Tikka and POF group sub MOA with 150gr. Sst superformance
My 2 rem 700 won’t hold 4”. Just have to shoot them to find out.
I spent several hundred dollars last year trying to find the best round for all my .308s
Ended up being 150 fusions. They grouped at least 1.5” so I standardized in all but the Tikka.
The SST is a Deer hammer if your gun will group with it.
