I picked up a used 70, 7mm rem mag, in a synthetic stock 4 years ago. It's the push feed type.
The first thing I did was shoot the rifle, it would stay barely under MOA with some loads I had good success with in my other 7mm rem mag.
I pillar bedded and Devcon Plastic Steel bedded the action, and added a nicer Vortex Viper to it, and then developed ammo for hunting with it, it now is probably my favorite rifle truth be known, like it so much I traded for another one exactly like it that had one box of shells fired through, (the owner did not dig recoil) . One of these days I may hunt down a 70 in a different caliber, but I'm almost at capacity right now and tough decisions will be made as to who's staying, my 70's will both be staying no matter what the heck goes....... I love these two rifles, also they have the old style trigger, that I haven't fiddled with yet, might this winter I guess...
