Frizzellr is right on the ball with this one. Its more hype than good. In fact the short mags are so popular I understand rifle manufacturers are rethinking the ultra mags because they are being outsold big time. Browning no longer offers any ultra mag in their 2003 catalogue.

I' ve only fired and have experience with magnums. Call me nuts but that' s the exposure I' ve had, I started my collection with a 338 and my last rifle was a 375 H&H. On the weekend I got the opportunity to fire the 7mm short mag by Winchester through a winchester rifle. It reminded me alot of my slug gun. Really loud and fast in the recoil action, maybe because the barrel was shorter and rifle lighter. It almost seemed uncontrolled because of how fast the powder burned when compared to my 300 or 375.

Just my personal perception, I have no numbers to prove it.

340,
