RE: 270 and 300 WSM's
I agree, the WSM's are here to stay. SAUM's, WSSM's and Ultra Mags will probably all die off before the WSM's IMO. They are marketed well, but they also make sense. My cousin works for Browning and reminds me all the time they are not hype, they are for real. Things that are for real tend to stick around, especially when marketed correctly and honestly.
