Now that you mention it, I recall doing the very same thing with the lug bedded and screwed in the forend - but - it was on the .376/06IMP barrel I put on that action to replace the .458 barrel.

I was running some pretty scary loads and that Fagen Reinhart stock didn't like those any more than the .458 2"'s loads- kept splitting. Now, it's coming clearer. Seems to me I did the crossbolts and forend lug at the same time - no more splits. I "kinda" remember sweating about silver brazing that lug on, even though I had some anti-scale stuff from Brownell's in the barrel. It turned out fine! That was LONG time ago - bit fuzzy - man - I was just a kid - of 30yrs. Many distractions happened in the next 33.
