Thanks for all the help. Mine's an NEF too, but a .223 heavy barrel. I realize that the higher end optics, even the better low end ones, have the best glass and stand the best chance of holding zero, but there's just not room in the budget for anything pricier than a mueller right now. So, as it stands it's either the mueller 8-25 mil, the Banner 6-24, or the simmons 44mag on closeout, but I'm leaning towards the banner b/c I can get it at my local shop. As for the lower power ranges of better brands, I wish I could but I need the extra magnification to compensate for poor eyesight and I intend to spend some time shooting targets so the extra power is nice. Maybe my next rifle will wear a weaver or a leupy, but that's a long time off.
