While I don't have a 270WSM, I've been shooting the 300WSM for several years now. I like the fact that I can produce the same ballistics of the 300WM at a powder charge that's 5-10 grains less than it's counterpart and save about half pound in overall weight on the rifle. Where the WSM lacks is on the heavier side of bullet selection. Since the case is so short, once you get into the heavier, and longer, projectiles they start to displace the amount of powder you can put in the case having to seat the bullets where the cartridge will fit in the magazine. Additionally, the WSM can be a little finicky from a hand-loading stand point, where the WM is pretty forgiving when finding the accuracy nodes, but it's not like you can't achieve excellent accuracy with the WSM. A quick look at ammunition offerings on Midway shows that they carry 26 types of 270WSM, 13 types of 7WSM, 38 types of 300WSM, and 11 types of 325WSM. That right there should tell us which ones are on their way out and which ones stand a chance of surviving since the manufacturers aren't going to produce something no one is buying.
