Shot some Hornady 200 Gr XTP's today with a charge of N110 well below their max in the PDF.
6 shots - 84 Degrees and seriously humid
Hi=1846
Lo=1844
Avg=1840
ES=2
SD=0
Only 6 shots, and probably not repeatable, but wow. Had three in a wallowed out hole at 7 yards, but had three a little outside the group as well.
A charge below their minimum gave velocities over their max.......
I will be pulling the one I saved down, and then repeating the test if the charge is what I logged it as. Could be a fluke. The sun was at a sharp angle on the chrono. I had one set of six .357's that was whacked out, but it was not consistent like these. High of 13?? and low of 4??. Don't remember exactly. Shot it again and it was normal for that load.
The same load of N110 with a 180 Gr XTP gave 1310 FPS last time out and 1816 today. Something was wrong.
Moral of the story? Don't always believe your chrono. (Humidity mess with it?)
