Hi guys, Looking for some help on what I need to mount my new scope. The rifle is a remington 700 in 300 RUM. The scope is a vortex viper HS LR 4-16x44. My first question is about the base. I want a one piece weaver base. Should I get the 15 moa slant or the flat base? I do not plan to shoot past 1000 yards. I lean towards the 15 moa just to have the extra travel but am worried about it making the scope sit higher than it needs to, and am not sure if I even need the slant to make it to 1000 with the 300 RUM and the 75 moa that thes scope offers. Your input please. Also, what size of the vortex tactical bases should I get? Low or Medium? Obviously I want the scope to sit as low as possible, but are the low rings going to be too low? Thanks so much for your help!
