OK here are the values, 90degrees 86% rel humid. 15ft elevation.
I shoot off the same rest every time. The chrony numbers are as follows;3358, 3348, 3355, 3352, 3364. Chrony is a gama master at 10 ft. It rained here today so unable to shoot. I have run thru everything that I do and cannot see anything I am doing different. All the brass is preped the same, same oal length, same bullet AND same lot and bottle of powder. I am shooting .304 rough measured 3 shot group average at 100 yds with this load, shooting 2.8" + at 100. Could it paralex? I am shooting with the scope at 20x. When I get back to the range, I am going to shoot at 300 and bring it up as close to 0 as possible. Once I shoot 3 , if it is consistant, I'll go back and shoot at 100 and 200 and see where my poi after the change. If I do adjust it 2 clicks at 300, it should bring it up to about 3.25+ at 100. There I go thinking again.
Guys, I appreciate you input , keep it coming.
