Is this normal from one 3-shot group to the next? I'm referring to the 3 groups at the bottom that I highlighted. These 3 are all the same load (Winchester Super-X 100 grain) at 100 yards off a benchrest with a TC Icon .243.
The point of impact seems to be shifting slightly each time. What could be causing this?
I can't complaint about group size, which is right around 1".
Also, I get a lot of groups with 2 shots close to each other and then the third further away. I assume the first two shots are close to each other then the third gets thrown off like a minor flyer but I haven't checked for certain yet (don't own a spotting scope). What could be causing this issue?
