I was at the range the other day working on a load for my son's .243 win. The one five shot group shot within a 1" square, but what concerned me was the first shot was at the bottom left, and last last shot was in the top right in almost a perfect diagnal line with each shot creeping from the bottom left to the top right. The load was 44 gr of reloader 17 with 85 gr Barnes TSX bullets.
What would be the cause of this, and is this a possible problem with the load or gun?
