I am looking to throw some quality glass on a remington sendero SFII .300 win mag. I will be doing a lot of target shooting at first to really hone my skills, then eventually hunting. I was looking at a Leupold Mark 4 8.5-25 power scope. I want something that has a decently high power and has turrets for adjustments, but from what I am hearing a lot of people think the Mark 4 is over priced. If there is something out there that is better for less, why not save the money. Any opinions? Oh p.s. what kind of mounts and scope rings would you recommend?
