I've done a lot of firelapping of ml barrels. When I bring the topic up or recommend it it's not unusual to be told that firelapping will destroy the barrel. Usually it turns out that they or someone they know used valve grinding compound!

However, I did get favorable results using ACTUAL FIRELAPPING COMPOUND on patches. They do more polishing of the lands than the grooves. It also helps clean up sharp edges on the lands which is the most likely problematic area when patches are being damaged.

Another "However", shooting conicals with said actual firelapping compound gives the best all around results. Especially with hollow base bullets but that's not a necessity. The compound is used most was this one.

Used it many times. Works great.

Lately I bought a wheeler lapping kit and some copper plated conicals and just wipe it onto the bullet and do it that way. Seemed to have worked a lot better.

I've used Verals (LBT) firelapping compound for years. Works great.

I polish all my bores, not by fire-lapping, but by turning a patch or a brush mounted on a range rod and loaded with polishing compound, using a drill for rotary polishing, then manually fore and aft 50 strokes or so for linear polishing. Results are more than satisfactory, and my method doesn't involve a trip to the range and shooting and messing about with a firearm under the disapproving gaze of a RSO.

I have the Wheeler kit but haven't used it much. I'm out of LBT and plan on getting more.

That's supposed to be the fun part.

Yes, looking down the bore with a flashlight and the gun pointed at my face tends to be something that makes an RSO nervous.
