Kevan - I have the same Ruger and wondering how you lightened that up? Mine is close to 10# loaded, lol. I have an MPI stock that's super light 20oz IIR but haven't installed it yet. That will save about 3/4# not sure what else ya can do.
My "mountain" ones aren't real lightweights
700ti 6.5rm, 700ti 280, 700mr 260, they are all around 7.5# scoped/loaded. Any weight I saved I used to put more scope - zeiss hd 5, and Nikon pro 5. Could lose almost 1/2# with different scope. My m7 XCR 300 is fairly light too.
