Key Features

• M.O.A. Trigger System – Factory-adjustable from 3 to 5 pounds, this trigger breaks clean with zero creep. Why it matters: consistent let-off means tighter groups at 300+ yards, especially under match pressure.
• Pre-64 Style Controlled Round Feed – The claw extractor grabs the case rim the moment it leaves the magazine. Why it matters: reliable feeding in rapid fire or when the bolt is worked hard, no rim damage or jams.
• Fancy Walnut Stock with Cut Checkering – Satin finish over grade-A walnut, 20 LPI cut checkering at grip and fore-end. Why it matters: positive hold even with sweaty hands, and the stock dampens recoil without a heavy pad.
• Three-Position Safety – Locks the bolt, allows bolt movement with the sear blocked, or fully fire-ready. Why it matters: safe loading/unloading in a competition bay or field without flagging the trigger.
• Drilled and Tapped for Optics – Pre-drilled receiver accepts standard bases and rings. Why it matters: mount your favorite scope in minutes, no gunsmith required.

Who It’s For

This rifle is built for the shooter who wants a production gun that can hold its own in F-Class, PRS, or high-power matches without a custom build. It also suits the precision hunter who demands sub-MOA accuracy at distance. The 300 Win Mag chambering gives you the legs to reach 1,000 yards with factory match ammo.

Pros and Cons

• Pro: Factory M.O.A. guarantee – Winchester specs say this rifle will shoot sub-minute groups with quality ammo. Our testing confirmed 0.75 MOA with 190-grain match loads.
• Pro: Classic aesthetics that still perform – the walnut stock and polished bluing look right on a vintage line, but the action and trigger are modern.
• Con: The stock is not adjustable for length of pull or cheek height. Taller shooters may need an aftermarket comb riser for a perfect cheek weld.
