Weatherby Select Plus Hammer Custom Rifle Ammunition 25 Wby RPM 107gr PT 3350 fps 20/ct

The Weatherby Select Plus 25 Wby RPM ammunition delivers magnum-class performance in a compact, lightweight rifle package. Built on the proven Rebated Precision Magnum case design, this 25 RPM round achieves 3350 fps with a 107-grain Hammer Custom projectile—combining flat trajectory and downrange energy in a cartridge engineered for the Mark V 6 lug action. If you're running a lightweight Weatherby or another rifle chambered in this cartridge, Select Plus gives you the velocity and consistency you need without the weight penalty of a full-sized magnum.

Weatherby partners Hammer Custom bullets with its Select Plus line for a reason: these are some of the most meticulously produced projectiles in the market. Each bullet is turned on a CNC lathe from a solid copper blend, then individually weighed and measured with a micrometer. That obsessive quality control translates to round-to-round consistency that shows up in tighter groups and more predictable terminal performance—critical when you're counting on every shot to deliver.

The Hammer Custom hollow point design is built for immediate, controlled expansion. Upon impact, the bullet sheds petals while the solid copper core and blunt nose remain intact, maximizing the wound channel and energy transfer into your target. This is ammunition that honors the flat-shooting advantage of Weatherby's RPM cartridges, letting you make confident shots at distance knowing your bullets are working the way they should.
