I was at the range yesterday shooting my sandby load of 300g xtp and 90g of 777 loose. I noticed first few shots did not hit the paper with a crisp hole. I assume, this is what I have read on here as described as a key hole. What causes the bullet to do this? Didn't do it on all shots but this is the first experience for me.
Old rookie,
I noticed one of my shot this AM also was Kinda long like it was keyholed or sideways. I looked at it carefully when I got closer to he target and it was fine. It was about 75 degrees here in NO. Va. this am, perfect for shooting. I think the crisp hole are in new cardboard, once you shoot it out it is no backing behind the paper targets. That is my theory.
