[QUOTE="MontanaRifleman, post: 867057, member: 11717"] The most accurate and correct way to do it is with a ballistic calculator that figures in the scope height above bore. You input the slant range and distance along with other enviro data and your scope height is already programmed in the ballistic profile. But in your case, no PDA and shorter distance shots. The other two ways you ask about are both fine in short to mid ranges depnding on steepness of angle and distance. Dial the MOA or dial the yardage. In short distances if you know the basic corrections for 30, 45 and 60 degree angles you can approximate distance close enough for a 200 zero. i.e., Your rifle is zeroed @ 200, your actual distance to target is 300 yds on a 45 degree slope. You know instantly you are within your point blank range so slope does not matter. Aim dead on. For a 30* your corrected horizontal range would be 260 which would require additional hold of a couple of inches. If you zero'd your rifle @ 300, any shot inside 400 yds at any angle is a no brainer dead on hold with a good flat shooting load. [/QUOTE]
