I agree with Stubblejumper. As the reloading manuals state, the 7MM WSM does not leave enough room for powder when using the longer 7mm bullets. This makes it quita a bit less appealing compared to the 7MM Remingtom mag. I don't think it will survive in the market. Its a great caliber if you can live with the 160 grain and lighter bullets. If you are not going to reload though you would maybe want to avoid this one. You would get equal performance or better with a 280 Rem.
