Home Forums Hunting & Shooting Gunsmithing Cleaning a old rifle

Johnn,

I just finished fixing up a customers 1903A3 that had a really rough bore, and a load of copper in it, That wasn’t returning any clean patches, but it doesn’t pretty well now.

Here are some before and after borescope pictures... I couldn’t drive a lead slug down it, but now once I did the copper out (reverse elec plating), and lapped it the barrel slugs like most off the shelf rifles, and the patches are almost clean. Lapping here is done with abrasives, and you only aim to restore performance, not remove all the pits which would make the bore to big.
