Hey folks:
Loaded some Accurate 2520 loads today and tried them out at 100yds... Went from 23.5g to 24.9g... 24.7 seems to be the best in my AR15 at about 2,700-2760fps.
This powder requires sight in of 10 Up and 5 Right.... at 100yds. whereas Varget at 24.9g only needs 8Up and 4 Right at 200yds... Wondering why the large discrepancy? Also wonder what the correction at 200yds would be for 2520 powder?
What gives? Is it the burn rate, or something else ... granted that the temp with the varget was about 70degrees and the temp this afternoon was only about 55 degrees...
Any suggestions? What sort of 2520 loads are others using for 100yds, 200yds and 300yds. in an AR15?
Thanks.
Jon Frost
