Why is there no coatings used in rifle throats to slow erosion?

[QUOTE="Coyboy, post: 575377, member: 3733"] aplication would be near impossible, remember the reamer is only cutting out a small portion in the throat, coating just that portion to satisfy the film thickness issues would do very little to prevent erosion in the groove and lands just ahead of the reamer cut. so You may prevent erosion right where the bullet sits but what about .020" in front of it? Afraid the best we have to date in Nitride treatment. And that has not been a popular option to date, I think popularity lacks a bit just do to the fact that many switch calibers or cartriges before they have worn there barrel out. [/QUOTE]
