thanks for the kudos although not everyone ( as my wife will tell you) appreciates my practical, pragmatic approach to things.
the front square bridge I rounded off was on my Bauska action 505 Gibbs - not the 404 Hein. My son also had a gunsmith do the same thing to his CZ 416 Rigby.
I enjoyed the article too. I'm reminded of a rifle I saw recently, a vintage Winchester lever gun (1886?). A bored cowboy with cabin fever had spent the winter using a file to turn the barrel into a kind of half octagon.
