I like the fact of the short casing. Makes chambering a round a little quicker and is supposed to be more accurate due to a short more equal powder burn.. I wouldn't see the need to have a 270 and 270 WSM in the same safe. I think if you give the Short Mags a few more years the customers will weed out the ones they want to keep. My guess is the 243 WSSM, 270 WSM and 300 WSM will be around.I also like the 25 WSM and 325 WSM..
