I have had no indication of that type wear in my Lehigh plugs or vent liners.
Are you sure the walls of the flash channel are clean? You will need a #21 wire drill bit to get the the correct size of the flash channel. If you are using a 5/32" that is just a bit small and will leave flash deposits on the walls.
I should also say that I only have about 5-700 shots through my most used Lehigh plug and liner.
