shot it have fun. Have had some luck with using valve grinding compound to fire lap real bad bores.
Yes I have thought about smashing some valve compound onto some soft cast bullets and fire lap it. Just don't have time. Most of my "rough" bore rifles clean up well after shooting a few hundred rounds of cast.
Probably not relevant, but interesting. Peter at our club had a Long Branch No 4 with a dull bore. Couldn't get it to shine up no matter what he did. We had a couple of boxes of 303 produced by the SA Mint in the fifties and he thought to see how fast you could put a couple hundred rounds through his LB. He and a couple of friends did just that. Called me over to listen: sounded like oil frying in a pan, couldn't touch the fore-end at all, it was that hot!
Looked through the bore, expecting to see darkness from fouling - the light almost burnt your eye out through the back of your skull, it was that bright and shiny! He never had a problem shining that bore again...

What happens is you fill the voids with copper fouling and all the shooting polishes the copper fouling.
I don't care about dullness. Ever old rifle that I have removed all the fouling from becomes dull. I figured a few "fire" lapped bullets would just knock down any rough spots a little quicker.
