Hey RR,
I have a .308 survivor, and love it. Like Mac said most of the match loads will give you pleasing results. It took forever to find a handload that mine liked as well as the 165grn Hornady light mag. If I could have found those a little cheaper, I would have given up on handloading for this rifle. Mine was putting the light mags consistantly into .75-1.25", depending on me. The only handload I have found that really works well for my rifle is 44.5 grns of Varget (YMMV, use at your own risk, this is safe for me may not be for you, and all other disclaimers) under a Hornady 165grn BTSP. If I do my part, these will hold an inch every time. If I went with any more powder, the cases started to stick. I don't know if this was due to pressure or a rough chamber. Either way, 44.5 was working well so I didn't push it.
