Notice the sift in POI between your two circled 5 rounds groups? It doesn't matter how close together the first five are if those five shift on the target (which they will). If you continued to fire five round groups you can take it to the bank that a 2+/- inch group will appear where those ten rounds groups are now.
To put another way- it looks like the circled five are a bit less than an inch? If you hung a target as big as those five, would you hit it every single time?
No, I wouldn't. But I would be very close with the first few shots, if not on and I am good with that. It isn't a target rifle and wasn't planned to be. It is shooting much better than I expected with such a light weight barrel and the few loads I've been able to try in it so far. I will watch to see if the groups shift POI in a significant way as I continue to shoot it.
