[QUOTE="steeltraps, post: 947293, member: 74752"] Im getting 3/8 moa from 100 to 1300 yards with RL-33 in 338 lapua imp. with 28 inch bartlein barrel. 3025 fps average. Tight neck . 0 free bore. 105 gr of RL-33 , 5 th from rifling. My 10 shot ES was 13 with fireform loads and 10 fps with 1x lapua. Just like MontanaRifleman i experemented with temp. I put my rounds in refrigotor though. Tested with heat gun 40 degrees to 80 degrees, the inside of my truck rounds and found little difference in sensitivity! Actually the only diff i saw was the 80 degree rounds had 2fps ES over 10 shots. The average stayed at 3020 Fps. I have Neco PVM-21 chronograph so i fell that RL-33 in my expericane is very good for where i hunt in alabama. I may try putting some rounds in our deep frezze and chronoing them just for fun:D [/QUOTE]
