first of all, unlike Remington and Winchester, Savage tends to cut their chambers on the minimum side of the window. So you may try cranking your die down about 1/16th of a turn to see if it makes the bolt easier to use. Also if your doing hand loads you may need to back off a half grain or so. The Savage bolt head is supposed to be a little loose, as it self aligns with the case head. Some folks don't like this, but there's probably three times that, that do like it. I would not buy an aftermarket bolt for your Savage as it just brings in another bunch of problems.
