I'm the type of guy that I think a lot of the membership here is--see a problem, find a way to fix it.
This seems like a feat that is so full of difficulty that isn't worth pursuing at first, but the same can be said for the distances that we now shoot game animals too. Once upon a time, you were considered a great shot if you could routinely hit what you were aiming at out to 300 yards. Now 300 is a total chip shot to most under normal conditions.
I just hate the idea of investing so much time and money into the most amazing cartridges that we now have access to, only to know going in that the barrel is going to be "shot out" with less than 1000 rounds in some cases. No one is going to "stop" throat erosion entirely with the technology that we now have. But if we could slow it down considerably, we could all play with our expensive rifles a little longer before having to reinvest all over again in the form of a new barrel.
Here's some light reading for anyone interested:
and a video on salt-bath nitriding featuring Joel Kendrick:
As was stated before, the salt-bath nitriding seems to be the best solution at the present time and fortunately for us end-users, it's in no way a new procedure. Apparently the idea struck defense departments sometime shortly after WWII. So there has been a lot of time to perfect it as a barrel treatment.
