have a couple lefever nitro specials that are not "on face". have used the paper of personnel checks to use as shims to see if the shims will bring the barrels back on face. the latch lever at a good position right of center and the shims on the lump bearing on the frame pin moved the barrels back on face and everything looks good. have not measured the paper shims yet. had intended to use the metal of steel feeler gauges cut and shaped to replace the paper shims. read several comment here on this subject yesterday and the opinions vary from no good to a great temporary fix. anyone out there have any experience using steel feeler gauge shims to do this repair and how long did it last?
