Hi guys I have a Remington 700 SPS tactical in .223 and I'm trying to work up a good accurate load using 69gr SMK w/ Ramshot Tac and or Varget powders. I don't know how to find the best seating depth for this rifle. I have tried the 2.260 oal and worked up to 2.300 but I'm not happy with the results (good but not great). Any suggestions?
