I finally got a load in my 243 to shoot that I was happy with so I thought. It shoots little under 3 inches at 300 yds on a warm barrel. The last few days when I can find a calm evening i have been testing to see where my cold barrel shot would hit and man am I in trouble. (for hunting) Well my 300 yd cold barrel shot is shooting 5-6in high and 3-4in to the right. After the first shot it will drop back down and shoot good. What can I do!!!!!!!
