I don't agree! I can't see the 270 or 300wsm going anywhere. NA has been reluctant to accept an 8mm cartridge so a little to soon to predict the 325's longevity.

The micro is a few oz lighterplus shorter, so I wouldexpect the recoil to be more rapid and the barrel to jump more in it vs the regular abolt (medallion or hunter). I have not shot a 325 wsm but it will producemore then your 25-06, whether or not it will be tolerable only you can determine that.

You already own a great antelope and deerrifle in the 25-06 rem, so look for a rifle that will meet your elk criteria. While the 308win is capable I would personally be looking at 3006 or 300's if you want to use the .308 diameter bullets. Since you seem to want a short action chambering the 300WSM seems like the logical step to take.

Good luck
