I have one. It's housed in one of the early model Winchester coyote m70's. I am a huge 7mm fan, and the WSM is an incredible cartridge if you reload for it. If you don't reload there are very few factory ammo options. I got lucky with my rifle and ended up with a fairly long throat. If you have a shorter throat and try to shoot the heavier, longer, higher bc bullets the bullets will have to be seated deeper and this could eat up a significant amount of case capacity. I'm not familiar with anyone currently manufacturing a rifle in this caliber, are you looking used or custom?
