The key will probably be sabot fit (I assume we aretalking about .50's). Orange mmp's(medium loose), black crush ribs(tight!), plain harvesters(pretty tight), and mmp 3 petal ez (medium) load have all been down the bore of the savage. What combo's have you been shooting with good accuarcy?

The orange mmp's will probably be best for you, but dont rule out the others if you are not happy with the accuaracy.
