I have noticed in our area as well that the gun shops are flooded with used 7mm Remington mags. I think the short mags are taking a toll on all of the long Magnums. People tend to like the effiecency of the short mags over the longer version. I never was a fan of the 7 Mag even though I owned four or five over the years. I prefer the 280 over the 7 Mag as there is very little real difference in the performance yet considerable less blast and recoil with the 280. Blast and recoil that I have no need for.
