BB, the Monarch scope you mentioned with the BDC reticle will work great on yotes but if you ever want to shoot smaller critters such as prairie dogs you should consider a mil-dot reticle. I have a Burris Blackdiamond 6-24X50 with ballistic mil-dot reticle that is top notch, it shows me .204 bullet holes in targets at 100 yds easily and the reticle is superb for shooting smaller targets. Remember though, the higher the magnification the better optical quality needed to give a decent sight picture which in turn means more money. Good glass isn't cheap but over the long haul is worth it, but don't buy more than you need. Just my $.02 worth.
