Rechambering a Model 70375 H&H to 375 Ruger, factory barrel?

[WildRose]

The longer I think about it the more I'm considering another .375 Ruger, but one purpose built for medium to long rage shooting.

The Ballistics of the round are just great, better than I'd expected when I got the first one and I keep thinking with another 6-7" of barrel 2850-2950fps with .270-280gr rounds should be more than "doable".

One thing I've considered is just taking a Model 70 in .375 H&H and having it rechambered to .375 Ruger. When I look at the case dimension differences it seems like a reasonable possibility but I'm not the expert on such things that some of you are.

Help me out guys, which is the smarter way to go, a rechamber or starting from scratch with a custom barrel?

The H&H is a good deal longer (about .250") so you'd have to chase the threads and set the barrel back that much to clean the chamber up. That is not easily done and most smiths will want to just start with a new barrel.

Hadn't even thought of the H&H being longer, much appreciated.
