Wouldn't then some of the new current substitute powders also then cause the same danger.
Without a doubt mostare hotter than BP and again can be accelerating the problem - but I am still inclined to believe this takes a lot of rounds - a lot more than most of us shoot.
I still feel one of the bigger areas of concern will be in the breech plug area of an inline - sidelocks the gas is pretty much sealed in except what blows back out the nipple and most nipples are replaced long before the cutting gets to be out of hand. Flnters you replace the vent liner every so often to defeat the same thing. Even the Savage breech plugs come with a replaceable vent liner. Inline breech plugs may be the weak spot once the cutting starts it keeps cutting in the same track (path of least resistance). Again, I think it is important to stop these gases at the face of your breech plug not in the threads.
I have included an crude drawing of what I am trying to say.
