RATIONALE: WSM is the highest-performing short-action case for 7mm, and has manageable recoil for most. Typical reloader performance is a 150gr bullet at 3100fps and factory ammo is readily available for non-reloaders. Note that the WSM case uses a LARGE SHANK Savage barrel, instead of the much more common small shank. Other high-performance 7mm's (e.g. 7mm Weatherby) could be built for about the same cost using a long-action donor rifle.
DIY steps: remove old stock, trigger, and barrel (using barrel wrench and shop vise.) Dura-coat bare action to match barrel (stainless.) Bed action to stock following You-tube instructions. Install trigger. Install new barrel, using go-gauge to headspace, and tighten with barrel wrench. Install new stock, and scope.
