using AR Comp with 120gn SMK's, I finally found a powder that gives me good velocity and accuracy, 27.4gns gave me a low 2482 HI of 2520 ave of 2505 33,37 ES 14.69 SD 27.1gns gave me a low of 2485 a Hi of 2507 an average of 2495 ES of 21.62 and a SD of 7.28, accuracy was 1.5'' @208yds in a 20mph wind!!!! from my 18'' 1&8 twist BCA side charging upper! I'm very happy with the results, 50deg temps, also to note not a pressure sign to speak of!!!! I also revisited the SWMR @ 29gns same bullet no pressure but the accuracy was not there! I also ran 2 A2495 loads were way to slow!!! upper 22hundreds for 27.1 and 27.4gns had a few in 2300 range @27.4, I don't need to search for any more powder I found it!!!!!! I knew my 18'' barrel could easily get 2450fps and it did and then some!!!!
