No but like I said, the rifle should do better. Quite a bit better. It was equipped with a large aperture rear sight and fiber optic front. Neither of which are conducive to fantastic precision. From reading the article, I don't think the author was quite as comfortable or familiar with the rifle as he should've been. I'm not real nuts about a large aperture rear sight mounted on the barrel anyway. There's no reason why that rifle shouldn't do 2" or better at 100yds with a proper receiver sight and something less than a ghost ring.
For the record, the rifle did record a best of 2.71"@100yds for five shots with 300gr XTP's.
