Quoted: surely i can't take away enough material in one spot to be an issue under barrel heat conditions can i? you know what i mean... the effects of barrel heat on a uniform vs. non-uniform barrel concentricity.

When you polish deep to remove pits or blemishes in the barrel, the metal is being removed in that area, it's gone. The surrounding area will be a different dimension. I would doubt that it would have much affect on the barrels "consistancy", but anything is possible.
If you decide to polish out the lettering, you are going to have to do some blending of the area around where you polished. If you don't, the barrel may not look right when you polish it up nice and shiny, the light and reflection will be off. Kinda looking into one of those distorted mirrors at the Fun House.
But remember, the more you blend, the more metal you remove, the less concentric your barrel is going to be.
The only real way to remove lettering or deep pits, and maintain true consistancy, is to recontour on a lathe.

suspecting even small barrel concentricity issues could ill affect accuracy, maybe i'll let the lettering go if it is etched deeply into the barrel... as i remember on the last ones i did, the warning across the top of the barrel was barely scratched into the barrel, but...
the whole reason i'm choosing this route is a blend of cost and results. i know there are much better set ups out there. most all cost more. after i've finished with lapping, truing, trigger/sear work, and some bedding and stock build ups, i've never had a unit that didn't shoot .5 MOA yet. this two i'm working up now will make 11... not hundreds or thousands like the big dogs, but still a fair amount of fun and success - plus the local tight asses will actually buy these and talk up my meager part time shop/hobby.
i don't want to make something "shiny" if i'm risking it's accuracy. maybe i should perform all the work on both and break them in, then after recording their performance, i'll polish one completely and the other partially and retest. this won't be absolute, but it may shed some light on how much is too much...
i think this is what i'll do.
thanks for the help all!
oh, and if someone has more suggestions, i'd be glad to hear them.
thanks,
