NM48 laid it all out pretty well. I'm not a fan of BDC reticles, either - and for pretty much the same reasons.

I tried - and still have - a couple of Burris FFIIs with the "Ballistic Plex" reticle (one of them a "Ballistic Mil-Dot", but the values for each subtension were so far off that I punched my chrono'ed data through LoadBase 3.0 Mobile and printed a new chart for each. And because they're dependent upon the environmentals being identical to those in effect the day I chrono'ed the load, any changes bring shifts in impact. They're okay, but prairie dogs and coyotes (rifles are a .223 and a .22-250) don't tend to line themselves up on the ranges indicated on my updated reticle charts anyway, so there's always some hold over or under involved. So, I generally don't bother. At most of the ranges I'm shooting at, holding just below a coyote's back or a prairie dog's head is almost always going to put them down.
