the heavier 300 gr bullets seem to be more consistant with the savages, try starting at 41 grs and work up to 45, 43 seams to be the sweet spot.
slower burning powders like H4198 @ 65 grs is a good load also with the 300 grainers.
I don't know what 240 gr bullets you have, make sure they're .452dia. the closer the fit to bore the better.
