The 7mm wsm will not outdo the 7mm rem mag. But just like the wildcats based off the 280 and 30-06 cases, the 7mm wsm is virtually the same performance as the 7mm rem mag in a more efficient case making all of those a very good choice instead of the powder guzzling 7mm rem mag. I still have one 7mm rem mag in my collection but it gets no work because my 7mm gibbs (30-06 case), 7mm jrs (280 case) and the 7mm wsm all have about the same performance as the 7mm rem mag with less powder, recoil and noise. They are all within less than 100 fps of each other and that is just not enough to matter considering the benefits of the smaller cases. When I want a magnum 7mm I go to my 7mm-300 wby or 7mm stw and step up well beyond the others for serious long range hunting. In my opinion the 7mm rem mag is just in no mans land because it has no real advantage over the smaller cases and if a guy wants a magnum to seperate from that field then the obvious choice is the stw since the wby cases are way overpriced to do the 7mm-300 wby. I understand the 7mm rem mag has been very popular for many years and I have owned several taking several animals with them. It will continue to be popular because of all the rifles chambered in it. I own and shoot about everything and have no biases so I just tell it like it is. I am sorry if I offend anyone but I tell the facts as I see them.
