$340 for an X7 new sounds like a good deal, and if it is the stainless model, a very good deal. TC no longer makes the X7 so they are going to get harder and harder to find.
My X7 is my first ML and I am pretty happy with it. My hunting sites have a lot of steep, wooded areas which is just what it was designed for.
Need to settle on a load for this season, either Speer GDHPs or the FPBs. Both are shooting well.
