Owners of the 307 Alpine ST in 25 WBY RPM are drawn to the high-velocity Weatherby RPM cartridge in a modern bolt-action package. The Alpine ST stock gets credit for being lightweight without feeling flimsy, which matters for hunters covering rough terrain.

The 25 WBY RPM chambering is niche, and some owners note that ammunition availability is more limited than mainstream hunting calibers. The muzzle brake on the 22-inch barrel is appreciated for taming recoil from the high-pressure round, though it draws complaints about noise and blast in close quarters.

The 307 Alpine ST trigger is generally well-received in owner accounts, with most finding it adequate for field shooting. A minority prefer a crisper break and swap it out. The overall platform is seen as a capable hunting rifle, though the proprietary caliber locks buyers into Weatherby or specialty ammo sources.
