Accurate-Mag...Anybody familar with their bottom metal

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

I'm doing this with CDI bottom metal and modified 300WM AICS mags on a 6.5-06 and Berger 140 VLD's. Stock should be back this week

Thanks Lonewolf, I'm planning to do the install myself,never done it before. If I find that there's a problem with Accurate-Mag's kit I'll check with them. Mine is a 300 Win. necked to 7mm with basically an Ackley treatment. It's on the net called the "7mm Valkyrie". I need almost 1/4" extra mag. length. Thanks again, Paul P.S. Keep me abreast of how yours is doing, .....later.:boom:
