My FB feed was full of the 7PRC fans the last few days. George Gardner shot 3 Elk, 2 nice bulls, this year with it. Gave it a strong thumbs up. A few of my other friends that used it have as well.
I sold my 7mm Mag a few years ago and just finished a custom 280AI. I'm not going to ditch that as I wanted one for a long time. But I suspect that the performance and the marketing behind the 7PRC is going to dry up some of the fringe 7mms, like the Saum, WSM, etc. I also think it will take a tad of 7mm Mag market share, especially from those who reload. In the factory ammo group, I doubt many are going to sell their 7mm Mags for the 7 PRC.
