Does anybody else think the 7mmWSM should have been called the 280 WSM?
Yes. I usually tell people when they ask what cartridge my Weatherby is chambered in, "It's a 280 Wby Magnum." I get some strange looks.
The best thing about shooting a 280 is that you have a great standard cartridge and you didn't jump on the 270 or '06 bandwagon to get it. Typically those who choose 280 Rem's don't normally care for the other two.
