I got 15 good shots on my H/R Mag the other day. It's a Level 7 stock valve with a 12 gram changer in the Vert ASA with Macro line right now.
(Here's an old pic, pre-Dye {snickers at all the Carter owners})

I just got a 3.5 and haven't filled it yet to see how that works. I'm running a Winchester hopper for ball feed. I have a two piece Dye 10" for a barrel. It looks a little rough but is very capable.
Sorry, no current pictures, no camera.
I played woodsball the other day with my 007. I would have slaughtered them with my Mag, even running twelvies. :P
