Would like to very much, in fact if the guy I use made 429 barrels I would bite your hand off for that 44 VHS reamer.
Sure I know I can get 429" barrels, but if I go to another smith I will need to discuss the project with them, wait about 3 months before they can be bothered to order a barrel, another 2-3 months before I can get a custom barrel profiled and then another 2-3 months for them to do it and probably another 25% for the pleasure.
If I use the guy I have before he will probably profile and fit it in 5-8 weeks, also I was thinking about doing it as a takedown too. A local guys says he can but seems a bit unsure of it, a couple of others have refused to do a takedown and the guy I usually use has said sure it seems doable enough!
He did offer to tool up for 408 or 429 for me, said if I wan to wait a year or so he will make me a 408 or 429 barrel!
So I can choice is 358, 375, 416 or 423!
I have a 38-55 and a 375w but I don't have any of the others.
