It was 28F when I shot...data was a little off from what I expected...I think I'll go out and test 12gr-17gr once the temp rises above 60F...I think it was more of a: "me get out of the house and go shoot" thing...than it was an actual gathering of good data...was fun...but now time to warm up with some KY Bourbon and watch YouTube videos of 300PRC rifles...since that is my next project.
