"isn't all the other stuff BS and making THAT harder than it needs be?"

It seems it is to hard, you should just stay with what you are comfortable with.

There has been some great advice and insight given here by some posters and it has been rebuked by folks that really don't have and idea about what they are speaking of.

If mils or moa or whatever just does not appeal to you then don't bother with it, make your call in inches or whatever you speak in.

I personally like the mil system and have converted most of my equipment as such.
In the end whether moa or mil they are just tools and if you want to be proficient in spotting hits at distance in a mils reference then the only way is to get equipment set up for mils and learn to use it.
