Horizontal spread could indicate an issue with the rear bag.
Definitely going to check into that. MD said something earlier about the sling studs and
I'm pretty sure my rear sling stud was on my rear bag, so I'm going to change my setup next time out. That right there explains it. I always remove them for load development.
If I had to place a bet right now, I'm going to say that the sling studs or something about my rear bag placement was the problem. I used to shoot better groups 10 years ago without even using a rear bag than what I was seeing with this gun last month.
