ive been using small amounts of blue loctite in the green tube (says "guntite" on the tube) on my base screws, most (actually all, now) of which are warne torx screws. ive swapped bases on several of my rifles, after ordering bases that didnt suit my taste (weavers were too aluminum, then weaver grand slams were too tall. now i just switched everything to warnes). did a lot of scope swapping last summer and found that the blue loctite does not make it particularly hard to remove the screws. anyway, with the torx screws i'm able to tighten them down really good, and i really dont think loctite is necessary (especially w/ the non-magnum loads i typically shoot). however, i put it on there anyway just as a sort of insurance. maybe its just a placebo in this case, but i dont think it hurts, either
