Re: question from a newbie about an action
No they are not all the same. Don’t quote me on this but I think the Howa is the same pitch as the vanguard which is 1.5mm which is metric. Remington, weatherbys, and most of the others use English like 16 tpi, 18 tpi, ect. But your smith should be able to thread a new barrel on the lathe and fix you up. You may want to ask them before just to make sure they can thread metric. I am thinking about doing something like you are but I have a vanguard in 22-250 which is the short action. I might take one of the spare Remington 700 heavy 308 barrels I have and rethread to the 1.5mm and use on my vanguard. Of course when I rethread it I will it will have to rechamber it and it will shorten the barrel but its 26” to start with so it’s not going to hurt taking off 2” of less.
