I've built a wildcat on a 116 action that was a 7mm Rem. Mag. and I need a longer mag to accept rounds that are 3.588"-3.590" OAL. Accurate-Mag makes a kit that has a trigger guard,mag.well, lift assy. and a 5 shot 3.850" mag. that has the mag. lips set for a 300 Win. Mag. I was told by them that Savage uses their products for their O.E.M. parts. Part #01200-0006-01 is supposed to fit my 116 w/staggered feed. I may have to open the bottom of the action a little bit to allow for the added length. Has anyone used or installed anything from them? Thanks, Ya'll have good one, Paul
