[QUOTE="DMP25-06, post: 1058035, member: 27271"] Hello CA30-06 , I have a Rem. 5R .308 with 24" barrel . Using Sierra Match King 175 gr. bullets , I initially developed a load using Varget powder , Federal 210M primers that I later changed to Win. Large Rifle primers because they proved to be more accurate than the Fed.210M , that chronographed at 2740 fps through a Magneto Speed 1 , and shot 1/2" groups at 200 yards if I read the wind correctly . Then I ran out of Varget . I switched to IMR 4064 powder that is equally as accurate , slightly slower [ 2704 fps ] , still using Win. LR primers , Sierra 175gr. Match King bullets , seated to a maximum cartridge length of 2.815" [ both powders ] . The only difference in accuracy that I have noticed is that the IMR 4064 is sensitive to temperature change , slowing as temperature drops . I shot my rifle in the Texas State Rifle Assn. 600 Yd. Mid-Range Match , F-TR Class [ .308 Win, or .223 Rem. only , maximum weight of 16# , my rifle , scope , and bipod weighed 10#7oz. ] in the fall of 2014 . Using my Leupold Mark IV , 4.5x14x40 LRT scope , shooting off a cheap Caldwell bipod , I maintained vertical accuracy of 1/2 moa , and shot a score of 1133 out of a possible 1200 , in my first F-Tr competition . I missed making NRA EXPERT ranking by 1 point [ I needed 1134 total for expert ranking ] . I was randomly put in a group with the eventual winner and runner-up of the F-Open class [ scores of 1199 and 1198 , respectively ] , both using 22 pound custom built rifles . Both of these shooters could not believe that I was shooting a factory rifle that was capable of such accuracy in pure , un-tuned , un-altered , stock form . The rifle is much more accurate than I am . I forgot to mention that my brass is Federal Military brass . DMP25-06 [/QUOTE]
