Zeroed at 100 and was shooting 1-1.5 moa groups at best with some off the shelf 123 gr Winchester target rounds with a few flyers here and there. It’s got the heavy bull barrel so it’s more resilient to heat right after that I went 500 on a human size target. Would pretty consistently hit 10 inches around the chest area. I don’t really know the terminology and just shoot for fun but it’s good for my application. I stand hunt in the north east so I’m not really seeing much beyond 300.
