I purchased a Vortex Viper 6.5-20x50 about 6 months ago and mounted it on my Remington .308. I have put about 400 rounds down range with it and the scope has performed flawlessly. I purchased a Remington 700 5R MilSpec .300 win mag about 8 months ago and I am ready to put a scope on it. Does anyone have any experience with a Vortex scope on a high power rifle. I am concerned about the pounding that it will take mounted on the 300 win mag. Any and all replies are welcomed.
