Description
The 25 Wby RPM was engineered to maximize modern heavy-for-caliber bullets, and this load proves the concept works. The 133-grain Berger Elite Hunter is the most advanced quarter-bore hunting load on the market right now. No other factory 25-caliber ammunition uses such a heavy, high-ballistic-coefficient projectile, which means you get superior long-range performance that other quarter-bores simply can't match.
Designed Around Heavy Bullets, Not Compromises
The 25 RPM uses a fast 1:7.5-inch twist specifically to stabilize the heavier, sleeker bullets that older quarter-bore rifles can't handle. That's the whole point. You get a rebated-rim design that fits the same bolt face as your .308 Winchester or 30-06, but with 40 percent more case capacity than the 25 Creedmoor. The cartridge delivers magnum-level performance in lighter, more compact rifles that actually weigh something you want to carry up a mountain.
The Berger Elite Hunter Advantage
Berger's hybrid ogive design blends tangent and secant nose shapes to optimize efficiency and reduce wind drift. These bullets feature a thinner J4 precision jacket built for rapid expansion on game. The 133-grain Elite Hunter penetrates 2-3 inches into vitals before expanding, then creates a devastating wound cavity. Tests show this load groups in the sub-MOA range from modern Weatherby rifles and maintains 1,509 foot-pounds of energy at 500 yards.
What Makes This Load Different
Weatherby Select Plus ammunition is built with premium brass, proven powders, and tight tolerances for consistency. Factory testing shows this load running around 3,000 fps from a 24-inch barrel, offering a real ballistic advantage where it matters most: at distance where traditional quarter-bores start to fade. The load was specifically designed for the new 25 RPM platform and delivers sub-MOA accuracy in Weatherby rifles.

Frequently Asked Questions
What rifles can shoot this 25 Wby RPM ammunition?
This load is designed for rifles chambered in 25 Weatherby RPM, which includes Weatherby Mark V rifles (including the Backcountry models) and the newer Weatherby Model 307 platform. Both use the standard bolt face found on .308 Winchester and 30-06 Springfield actions, so if your rifle is marked for 25 Wby RPM, you're set.
How does the 133-grain Berger Elite Hunter compare to other 25-caliber hunting bullets?
The 133-grain Elite Hunter is heavy-for-caliber with a .631 ballistic coefficient, which is significantly higher than traditional 110-grain quarter-bore loads. This means flatter trajectories, less wind drift, and better energy retention at extended ranges. It's the first factory 25-caliber load to offer this weight and BC combination.
Will this ammunition work in older 25-caliber rifles like a 25-06 or 257 Magnum?
No, this ammunition is loaded specifically for the 25 Weatherby RPM chamber. Using it in a different 25-caliber rifle could result in dangerous pressure spikes. Always verify your rifle's chamber before purchasing ammunition.
What kind of game is this load suitable for?
This load works well on medium game like deer and antelope, and the retained energy makes it effective at ranges where many traditional quarter-bore loads start losing steam. The bullet's design allows ethical shots at distances most hunters rarely attempt, thanks to the flat trajectory and wind-resistance of the 133-grain projectile.
