I'm not too impressed with the new short magnums, from either Rem. or Win. Like otis said, magnums should be used for large game, not deer sized game. I bet that a competant handloader could make a 30-06 (or any caliber derived from it, .270,.280 in this case) outperform the WSM's and RUSA's in their respective calibers with bullets on the heavy end of the scale. It would seem to me that with a cartridge that short, a heavy-for-caliber bullet will have to be seated so deep that it will take away a good chunk of powder capacity. Now with bullets that are suited for smaller game, 130gr. .270, 140 gr. .280, and 150 & 165 gr., .30, I'm sure the Short mags will outperform. But I'm not a fan of a bullet that will blow up immediately on impact, and some bullets will at these velocities. I'll just stick with the cartridge I know and trust, .30-06
