Bought some Reloader 10x loaded up some 32gr V-Max and went to the range for some testing. Ended up with a load of 27gr of 10x for a max load which was also my most accurate. Avg of 4010 fps and just over 1/4" for 3 shots.
Also tried some XMR 2015 and again ended up at my max load being 27gr and most accurate. Avg of 4030 fps and just under half an inch for 3 shots.
The 27grs is the max listed I could find for XMR 2015 and half grain over max listed for 10x. Saw no signs of pressure at all.
Interesting thing was I also shot some factory Hornady in 32gr V-Max which lists on the box 4225 fps over the chrono. Avg was 3885 fps. Not sure if Hornady is fudging their numbers or if someone put some 40 grainers in the wrong box or what. Also not sure what barrel Hornady used but 400 fps is a big deviance. I am shooting a 24" barrel.
