Description

The TAC338 is specifically designed for cartridges with a .585″ rim diameter such as the .416 Rigby, the 338 Lapua Magnum or the 378 Weatherby based cartridges. The TAC338 is also larger than the standard TAC action. It is 0.050 larger in diameter and 0.465 longer. That is needed to accommodate the 0.750 diameter bolt that is necessary for these cartridges. The TAC338 actions have no feed lips and use only center feed box magazines. Bottom
metal with magazines are available from a variety of sources. The TAC338 actions use a straight bolt handle with a threaded bolt knob. It comes standard with a small tac knob that can be swapped with aftermarket bolt knobs by the user or a gunsmith. One piece picatinny rails with 0, 20 and 40 moa cant are available. The bolts have a new proprietary coating that makes them as smooth as glass.
