The TAC 338 is designed for cartridges using a .585-inch rim diameter — typical examples include .416 Rigby, .338 Lapua Magnum family, and many 378 Weatherby–based cartridges. Always confirm specific cartridge dimensions before final build.
No, the TAC 338 has a larger footprint: +0.050″ diameter and +0.465″ length compared with a standard Rem-700 style action to accommodate a larger bolt face and stronger locking surfaces.
The TAC 338 fits many big-bore stocks and chassis, but because the footprint is enlarged you should confirm action-screw spacing and inlet dimensions with your stock/chassis manufacturer before finalizing the build.
Current lead time is 12–14 weeks from order.
This allows any barrel ever fitted to a Stiller Action to be screwed onto any other Stiller Action without any need for re-headspacing or re-indexing.
