[QUOTE="7magcreedmoor, post: 1016162, member: 48559"] A clarification: will sfp be accurate at other magnification than the one specified? The value of the subtensions will change with the power selected. Is it accurate? Yes, but at a different distance now. I have both kinds of scopes, and in the SFP model the first hash below center is 1.5 moa at maximum magnification. Drop the mag to half, and the hash is now 3 moa. 1.5 moa might be my drop at 275 from a 200 yard zero, but 3 moa is 345. You can work with any system if you put in the time to check all the calculations, and it will be "accurate" as long as you are using the right magnification for the right distance. With FFP, you only need to do the math one time, because the subtensions are always the same, no matter the mag setting. Look at the available reticle patterns in person if you can before buying, and check at all mag levels if previewing FFPs. My Vortex Viper HSLR FFP is good for everything from snap shots in brush at 30 yards to beating steel at 1175, I've done both with it. Others will say SFP only and forever. It comes down to personal preference in the end. [/QUOTE]
