Rem 700 long action same as mag action?

[Orcon]

If you're any good at measuring stuff you can take measurements on the receiver and send it over to Pacific Tool and Gauge to make you a new bolt with a magnum bolt face. They're slow as hell and customer service is not the finest in terms of communicating your order status but it always shows up and it's good work. After that, all you need is an action wrench, barrel vise, barrel, and *presto* new rifle.

Edit: Don't forget your Go/No Go gouges.
