I got my Chrony back. So I mounted it on a Tripod. So It's lower then the stand so no risk shooting it. Now I can chrony and group.
Love the car jack rest, don't have to worry about that one wigglin' around.
Is that a jack stand?
@RobertMcC what gun? My Fire NP has similar ups/downs, and this daisy buck bb gun. After they sit for a while, the first shot ends up being 30-50 fps higher than the rest of the string, then drops to its lowest point and works upwards to a stall in fps.
