I shot a 338 win. with the 2.5x10 extreme classic on it today. I will report that everything worked as advertised. Optically it was every bit as good as the Leupold 3.5x10x50 I shot today on a 300 Rem SAUM. Both scopes are new to me, first time shooting with them, and I really like them both. Did not do any accuracy work just got them on the paper and shot a couple of groups. Was pleased with both and look forward to warmer weather and more time at the range.
