My savage 10 FCP McMillan likes all kinds of ammo. I can probably shoot 5 different rounds and keep under an moa! that may be slightly exagerated. My go to load is 43 gr varget with a 178 a-max, oal ~2.787 it consistantly shoots around .2-.3 moa out of black hills brass. My best group however was at 41.2 gr varget in federal gold brass with 175 smk. all with cci br2 primers. Hope this helps. The best group i ever got from factory ammo was from Hornady match 168, at .210 moa. all these groups were at 100 yards. I have hit 12" or < diametrer rocks at 1163 yards with the 43 gr load, and have taken hogs at 500+ yards with it as well.
