No shortgrass, I was "after" a creative discussion with people throwing out ideas in the hope that we might just learn something. If somewhere along the line we're fortunate enough to actually come across something that has merit and could be pursued, then great! But if not, we can all still learn from each other.
On the specific "replaceable throat" concept, I was HOPING that someone with real gunsmith experience could say....."might be cost prohibitive, but could work".....or..."it's not going to have the outcome that your looking for BECAUSE........" So if you have a real-world perspective on what's wrong with it, please chime in. But just saying "Are you after Minute of broad side of the barn...." doesn't allow us to learn much.
You may be so much more intelligent than me, that this idea seems like some sort of cartoon to you, but I'm actually serious about learning something that I've never known much about. So please feel free to contribute or not contribute. But can we do it without sarcasm?

A little history : There have been many coatings over the years that were designed to prolong

A lot of the military weapons have been coated with one thing or another. The chrome lining
has the best track record for the prevention of erosion and corrosion. they even tried using a
Stellight process (This Is some very hard stuff) but apparently it was not a practical solution
and to costly.
I personally think that the throat erosion on most weapons is a by product of our need for speed
and therefore self inflicted in most cases. Before all of these High velocity cartriges throat erosion
was not a consideration and most rifles lasted a lifetime.
We have become more interested in velocity and accuracy and that has changed things.
It is simple physics: the more velocity, the more powder, the more powder the more erosion.
If you build a hot rod you can expect this problem sooner. Setting the barrel back is a simple
and proven fix. re barreling is the next thing that can be done and accuracy maintained.
I have seen barrels with the throat completely gone for several inches still shoot well because
the barrel it's self was taken care of and maintained.
There may be a coating out there waiting to be discovered that will double the life of the barrels
accuracy but for now IMO a good smith can restore a rifles accuracy better.
Just my comments on coatings.

J E........thank you for giving us your thoughts! I for one definitely appreciate you taking the time.
I agree that our human need to "push things" (oftentimes past the practical limits) is what has led us to where we are. Good point.
It seems as though the military has actually spent a great deal of time and money on this very concept. Do you feel that their needs and our needs are different enough that some of the coatings that they've found less than suitable might actually be beneficial to us?
What I mean by that is----they're going to need coatings that can stand up to rapid-fire/sustained fire scenarios where they'll be generating a case for much quicker erosion. Has the TYPE of firing had any bearing on their experiments? I don't know. Do you?<---that's NOT said in sarcasm...lol.
If not......maybe that's something that I should research more?
Again, thank you for taking time out of your day to lends us your perspective. It's really appreciated.
