Exact same set-up as the SSX test. 40 yards from shooting sticks. Same POA, base of neck.
Given that the 3.5" XR is sending 400+ pellets downrange, I am still not thrilled with these patterns, but they are somewhat better than the average SSX patterns:
I will still keep looking around, but I this is what I have been shooting for the past few years. I see no need to change unless I find something better.
