I got a ptr mgs91 a few weeks ago and I picked up a Leopold rifle man 3-9x40 to see how it would do in the meantime. I was shooting on a flat range the wind was about 5mph left, after sighting it in at 100 yards I went straight to 630yards and I made the 1st 3 rounds that spread across the plate to get adjusted then I took another 3 shots and made a 3.5" group. In the picture I have a different setup then when I was shooting I had a harris bipod on and the leopuld I returned.
