If the roughness that you are talking about is sliding the bolt back and forth you can get a DMT diamond medium sharpening hone. It is about 4.375 long and .900 wide. The top is hard to get to but the bottom rails are pretty simple to clean up. You will be surprised at the roughness of the lug rails on some Savage actions. I use a very light oil as a vehicle to remove the metal away from the cutting surface. Scrub when done. After that, a little lube does wonders. .........If you are talking about bolt lift, SSS T&T is a bargain. The ramp is too steep so the cocking ratio gets reworked from something like .250 to .200 in <90 degrees rotation. Rayhils lift kit (with some grease) combined with shortening or "shimming" the BAS for adequate but not overwhelming firing pin spring preload helps if you DYI.
