The range is up against a hillside and we were there in time to catch the morning winds cut through the range...it was windy and COLD (well, cold for SoCal
.) Also noticed I was shooting slightly downhill. When I put my target out to the 50 yard line, I noticed I leveled out. Also, I did most of my shooting sitting down which took some getting use to. Normally stand, isosceles stance.
Thanks for the input. I didn't realized so many little things added up to so much. In that light, I'm pretty glad I did as well as I did.
