NEW for 2008
The idea of shortening a magnum case, and increasing performance by optimizing a case's geometry to deliver more power with less powder began with Lazzeroni back in the early 1990's.
Winchester introduced 7 different Short and Super Short Magnums, (3 WSSM & 4 WSM) in the early 2000's .
Now Ruger and Hornady have developed two "Proprietary"
Short Magnums, the 300 RCM and 338 RCM, RCM for
Ruger Compact Magnum.
150 grain projectile = 3,627 FPS
180 grain projectile = 3,597 FPS
and slightly beats out the
300 WSM |
