I know this subject has been beat to death, but I have always used the old J-B Bore cleaner to try and take the "edges" off some barrels. Now I see they have J-B Bore Bright Paste. Which do you think would work better? I also see Montana X-Treme makes a polishing compound paste for bores. I have never felt I gained much when I used J-B in the past so I am a little apprehensive. One problem is my gun is shaving sabots at the muzzle and I don't think the j-B will hit the right spots unless I work it from the muzzle which I don't want to do. I may just have the crown re-done. Any thoughts?

IMO, look at the crown under magnification, or take it to a gunsmith. The muzzle is too important to mess with! Even when I lapped my first Savage, I stooped short of the muzzle. Inconsistencies throughout the bore can be tolerated much better than at the muzzle/crown. edge. PS not only did I stoop short, but I stopped short too  |

Any thoughts? SW has talked of using an appropriate -sized marble with some 220 grit lapping compound to touch up the muzzle and remove small defects. Followed by the same traetment with 320 grit. |

I have both JB bore cleaner and JB bore brite. The bore brite is used after the bore cleaner to polish the bore. The bore bright recommends 40 to 60 strokes after using the cleaning compound.

As was mentioned above, a marble or what I use is a ball bearing. I place the ball bearing on top of a piece of 320 -- 400 grit. wet/dry sandpaper. Kind of grab the paper and ball bearing and rotate them back and forth and keep moving the ball bearing to a new spot on the paper. If you had a way to keep the barrel turning (such as a lathe) you could just press the sand paper into the ball bearing against the crown. I usually do that after I have cut a new crown anyway.

I used the JB paste and did not stop short,with no ill effects.This particular Savage is my sons.It was ever so slightly shaving sabots.It does not do it since the JB paste treatment.This gun shoots extremely well.It is the most accurate Savage I have seen or shot to date.I use a .45 cal brush wrapped with a patch and make single one way strokes from breech end.I see no harm in doing this if it is not done excessively.This gun has not suffered.Sub moa at a 100 yds and moa at 2-300 yds.

Richard Richard so just go to the hardware store and some 320 - 400 grit sandpaper and push the marble as the guide and round the edges off? Sound easy enough. Worse case if I screw it up it is not hard to have a barrel recrowned. |
