Thanks again Daryl.

So, worst pitting is in the chambers,and what of the muzzle? if pitting is very bad,is there risk of a barrel blowing? or are such barrels too thick for this to happen?

1mmx1mm pits for example,are able to be polished out then i take it? Does this polishing involve much removal of metal???

By polishing the lands, does this not effect the caliber size?

Danzac,hmm, interesting.........could be the answer.
