I would like to load some 180 TTSX in 308 win. I would like to use IMR4350 but don't see any recipe's for this in the books. I also have access to IMR 4064 and I do see a load for the 165gr TTSX but not for the 180's. Anyone out there with experience shooting 4350 behind a 180 in the 308? I would like to keep it above 2500 fps.
