Now, even if I knew exactly how I would procede were I in your friend's situation, which I do BTW

, I would not state it here. (See previous post)
What I would say is that if your friend has such a burning desire to hunt with this rifle, he should first build a BP ML himself. And I don't mean putting together a CVA kit. I mean buy the barrel and other parts needed, fit the breachplug, cut divetails with a file, fit the metal to the stock, the whole nine yards! Okay, he can use a pre-inletted stock...

In so doing, and by also doing the research required to perform each step, he will become intimately familiar with the workings of a ML! Lock, Stock and Barrel!

When he's done that he will be better able to make an informed decision on wether or not to fire his old rifle. And just think! He doesn't even need to buy a set of headspace gauges!

I'm reminded of an article I read a number of years ago.

It seems the author was in your situation and after a visual inspection fired the rifle. Upon firing the breachplug promptly blew out.

Visually the area looked fine, but unseen was the rust that had eaten away much of the breachplug/barrel threads. He shouda known better then to let that happen! Especially in such a critical area.
