Sighting in Burris scope on 270 Remington WSM

I just got a new Remington 270 WSM along with a Burris Fullfield II 3x9x40 scope. This is my first rifle with a scope & I am trying to get some helpful hints at sighting in since I have never done before. I have read the instructions & gathered some information from the salesperson, so this is where I am at.....
I am going to zero it in at 200 yds.
I will be shooting the Winchester 130 grain ballistic round.
Will I be able to shoot out from 50 yards & would this be pretty close to zero at 200 yds? Sorry to sound like an idiot, but like I said, I have never sighted one in before & I am looking for ANY helpful suggestions.
Thanks

How do I use these two charts to sight in rifle? THANKS
That aside, I set my 270WSM 2.4" high at 100yds, which gives me a zero at about 265 yds. at 8000' altitude. Highest point is 3" at 150 yds. and I'm better prepared for longer shots. Not knowing how long your shots may be, I'd recommend you sight in at 100 yards, since the parallax on your scope is set at the factory for about that range, (not 50 yards) and adjust the scope so you hit about 2" high. For a deer-sized target, you should be able to hold right on up to about 300 yards. That's a great combo you have and with some practice at the range, you can forget about canned data and start thinking about where on the wall to mount your trophy.
For all practical purposes, those ballistics listed by Winchester, and the calibrated ballistic curve of your Burris scope, will be close enough for what you are looking for. Bore sight your rifle at close range...like 25-50 feet, by removing the bolt from the rifle, and placing the rifle in something solid where it can not move, and use the procedure posted by beeramid.
Next take it to the range and put it on paper at 25 yards. Adjust your scope so it is dead center at 25 yards. this should put you very close at 200 or close enough to be on the paper. I usually shoot at 100 then 200, and then 300 yards just to check and be sure I have a grasp on the trajectory. Both the Winchester and Burris literature are telling you to sight in so you are hitting 1.1-1.2 inches high at 100 yards and you will be 0 inches or dead on at 200 yards.
Ballistically speaking, there is not a real bid difference in trajectories of the standard belted magunm rounds from 6.5mm to 338, out to 500 yards. Just make sure your scope is square to your bore, and you have it mounted as low as possible.
