I am looking for a gunsmith to convert a 300 WM to 375 H&H and was wondering if anyone here has a gunsmith they use/recommend for such things ?
Thanks

Jim Kobe (JKob) has always done good work on my model 70 projects.

Mark Penrod does great work.

Pre or post '64?

Kevin Weaver has done a few good ones for me.

I'd also recommend Jim..

More than likely a post. If it were a pre, he'd be better off finding an H&H receiver or rifle to convert to 375. Or just buy a pre 64 375 H&H..

I hope he’s not changing a P64 300 Win over

If it’s a post, don’t much matter. Done a few and they’ve worked fine.

Exactly.

Mark converted my 375HH to 416 Rem. He does excellent work.
