For example, an average 168 grain 308 load or 75 grain 223 load can be easily sighted in to where one mil low = 300 yards, two mils low = 400, and so on, which makes for a really intuitive BDC reticle. A reticle with MOA graduations isn't going to fall in line so nicely.
You know they have an app for that, actually several and they seem to work pretty well. Seems to me an MOA system will mirror pretty closely to what you can do with a MIL system, but the yards or meters per dot/hash might not be the same. All it boils down to is I don't want a BDC reticle calculated for some cartridge I might not be using, I'd rather just have a plain MIL or MOA reticle where I figure it out.
