With 100's I would look at Varget, Big Game, RL 15 and any of the 4350's. H 4350 and H 4831 sc have done very well for me in the past with 120 gr and heavier bullets. From your list of bullets the 125 gr Pt and 140 gr Bt would be the ones I would look at if the 100's don't work. I have a LH Predator Max 1 on order in 260 Rem to replace my old gun, hope it comes in soon.
