PC bullets may be the best thing for handguns since gunpowder was invented but I have some questions no one has ever answered about these things. The big one is does it deposit in the bore even microscopically? If it does is it removed with cleaning or is it there and continues to build up. I just keep remembering the moly bullet claims of a few years back that ruined some rifle barrels and turned out to be impossible to remove. Before I jump on the PC bandwagon I need these questions resolved by an authoritative source. I have other concerns as well but these are the two biggies.
