Looks like a good group but you need to show a picture that compares dimensions like a quarter or a measurement tape. It looks like at least three of them are sub MOA. Generally a three round group is good for measurement. I picked up a T3 in 30-06 last year when I stumbled across one at a gun show for a screaming deal while looking for a 30-06 for my son. That one is sub MOA with the Express Core Lokt 165gr Remington load. It has taken one elk, one deer and is definitely a keeper. It looks like your rifle is also.
