[QUOTE="Jimbeaux82, post: 1150141, member: 93815"] Thanks ! It's hard to wrap my head around that one scope handles all they rounds that are out there ? You basically have only 2 scales to worry about and adjust for: 1) standard cartridges like 243 Win, 308 Win, 7-08, 30/06, etc. 2) Magnum cartridges like 264 Win Mag, 7 Mags, 300 mags, etc For the standard cartridges you usually zero main cross hairs for 100 yards and each successive mark is 100 yards farther. For the Mag cartridges, you zero main cross hair for 200 yards and each successive mark is 100 yards farther. This just highlights how close in trajectory most cartridges are within each group. And the system works because they use the full "kill zone" of an animal. They are calibrated such that out to 500-600 yards you should be in the kill zone with any of the cartridges. It will not be an exact 'zero" but close enough to hit in the kill zone. That is how the systems work. If you want an exact zero, your only option is to spin dials and use that system. I personally like the BDC systems and find them faster than spinning dials and sufficiently accurate out to 600 yards to fit my needs. If I were shooting over 600 yards, I would spin dials. But to each his own. All that being said, it is best to actually check the impacts with your loads at the various distances to confirm. I have done so with several of my rifles and have been pleased with the results. Jimbeaux [/QUOTE]
