To start; don't treat your Savage like a Remington, because it is not. Lapping the lugs will only prematurely wear out the bolt head, and will accomplish nothing as far as smoothing out the bolt travel, and make better contact. The Savage design uses a floating bolt head, and will make 100% contact on firing. There is still a way to use a gunk button (AKA bolt lift kit.) with the accu-stock rear cocking indicator guns. SSS sells one.

If you want a gun that is perfectly smooth and needs no addition work well your in a dream world. Even high end custom actions such as Pandas, Bats and so forth that run $1300 need some work. Bad news is no matter how much polishing you do to your Savage parts it will not "slick up." The hard bolt lift associated with Savage actions is due to geometric configurations in the action that need cut at different angles, to achieve a truly smooth bolt lift.
