Re: Advice on a Marlin x7 .308
just b/c it's a cheap rifle doesn't mean you should skimp on optics. My marlin is still getting figured out but it's got a couple sub 1/2" loads that it really likes. I have ground off the pads at the front of the stock and completely floated the barrel. Nikon,Leupold, etc...the usual bandits. Have seen some good deals from Cameraland lately on the Vortex line too.
Enjoy that rifle...most shoot better than the guy behind them, and they ALL seem to like Federal blue box ammo. mine will do 1- .75" all day with blue box 150 gr's.
