Looking for advice on mounting on rmr. Currently have a sig whiskey 2-10 on a 277 wolverine and am wanting to mount an rmr to keep zeroed for subs. I've looked at the warne ramp, burris xtr rings, and swampfox mount. Also looked at mounts that attach direct to scope tube. I'd prefer to keep it mounted at 12 o'clock so as far as durability what have you found to be the best mounting solution?
