Not too many years ago, Ross Seyfried wrote an article about hunting moose with a 6.5x54 Mannlicher, IIRC. Oryx bullet, which he had altered slightly with small cuts in the jacket at the nose to make it expand just a little faster.

One shot, one moose, and it only took a few steps.

Now that I think about it, I think it was a rifle he'd bought off of Ken Waters. Neat article. Close enough to the 6.5x55, I'm thinking.
