Remington 700 Sendero .338 RUM with a Vortex Viper PST FFP 6-24x50 I am going to go with the Seekins Base and Rings. Couple questions before I place the order. 1.) I want to stretch this set up out as far as possible. Doing the math with a 200 yard zero it looks like at 2000 yards I will drop about 95 MOA. the scope has 65 MOA total travel. I'm thinking a 30 MOA rail would be the best option. does this sound correct? 2.) The bases come in #6 and #8 screws. I believe for a factory 700 action a #6 is required but wanted to be sure. Thanks, Speedy.
