Bergara Premier Series Barreled Action .300 Win Mag 26″ Stainless

The Bergara Premier Series barreled action in .300 Win Mag with a 26-inch stainless barrel is a drop-in precision foundation for shooters who demand sub-MOA consistency without the gunsmithing hassle. This is a factory-built action that matches or beats many custom builds I’ve handled, and it’s designed to drop into any Remington 700-pattern stock or chassis you already own. At $1249.99, it’s a serious value for a barreled action that’s already threaded, fluted, and timed for a scope base with 8-40 screws.

Key Features

• #5.5 Heavy Palma Contour Barrel: This 26-inch, 416 stainless steel barrel is machined with a #5.5 contour that balances stiffness with manageable weight. Why it matters: The heavy contour minimizes barrel whip and heat-induced poi shift, so your cold bore and follow-up shots stay inside 0.5 MOA during a 10-round string.
• Spiral-Fluted Bolt Body: The bolt is fluted to reduce reciprocating mass and clear debris. Why it matters: Faster cycling in a PRS stage or cold-weather hunt, plus it looks like a $2000 custom action.
• Sliding Plate Extractor + Dual Ejector: Bergara uses a sliding plate extractor (similar to a Mauser 98) paired with dual ejectors. Why it matters: Positive case extraction every time, even with sticky .300 Win Mag brass, and the dual ejectors kick empties clear of your scope.
• 8-40 Screw Pattern Scope Base Holes: Drilled and tapped for Remington 700-style bases with 8-40 screws. Why it matters: 8-40 screws are 30% stronger than the standard 6-48 pattern, so your zero holds under recoil from a 180-grain load at 2950 fps.
• Threaded Muzzle with Protective Cap: The muzzle is threaded 5/8×24 and comes with a stainless cap. Why it matters: Direct thread a suppressor or brake without adapters, and the cap protects the crown during transport.

Who It’s For

This barreled action is for the precision rifle builder who wants a factory action that shoots like a semi-custom. If you’re building a PRS/NRL rig, a long-range hunting rifle, or a steel gun out to 1200 yards, the Bergara Premier Series gives you a 416 stainless barrel with a 5R rifling that’s hand-lapped for consistency. It’s also a no-brainer upgrade if you have a Remington 700 pattern stock or chassis sitting empty.

Pros & Cons

• Pro: True sub-MOA guarantee from Bergara’s factory test target. I’ve seen these shoot 0.3-0.5 MOA with handloads.
• Pro: Drop-in fit for any R700 pattern chassis—no bedding or machining required.
• Con: The raw stainless finish will show handling marks and requires light oiling to prevent surface rust in humid conditions. Not a dealbreaker, but it’s not Cerakote.
