In truth, I haven't fired that many different combos but both of my Accura like the 300 grain .452 XTP in Harvester Crushed Rib sabots and the 10mm 200 grain XTP in blue MMP sabots. I only tried 90 and 100 grains volumetric charges of BH209 and the rifle (and I agreed with it) seemed to favor the 90 grain charge. When the weather warms a little, I'll play with some more loads.

I would have bought one in .45 if they had offered it without the thumbhole stock.
