All Weatherby RPM cartridges have a rebated rim of .473" diameter with a .500” case body. These are basically the .284 Winchester case head and base dimensions. This case design allows using standard 30-06 Springfield/308 Winchester bolts but have a larger case capacity at a given case length.

With an overall length of 3.34", the 25 Weatherby RPM is a standard/long action length cartridge that, according to Weatherby, provides magnum performance. The new 25 Weatherby RPM is designed with a focus on shooting heavier, high-BC bullets: the recommended twist rate is 1:7.5" and the case length of 2.4” results in ample room over the case (.94”) for those long ogive bullets.

wby at it again as they always have to have the biggest hotrod per caliber............................the case capacity is ridiculous as barrel life will be between 500-800 rounds for accuracy. i'll stick with the 25creed as the 257rob+p doesn't have enough for the heavies and i could get over 2k rounds easy on barrel. just not for me, but those 1/4 bore peeps will be all over it. i'm passing on the 22creed for the 22-250rem (non-ai) just to have more barrel life.
 
Manufacturers got to keep making new stuff to sell! This one....can't see where it's a "better mousetrap" than what we already have available, but no one in marketing lives and dies by that philosophy.

Bullets matter more than headstamps. But yes, nice to see developments in the quarter-bore space.
