As it seems customary for any query in this damn message board to be preceeded with some kind of apologetic disclaimer regarding a previously asked question (even if it was researched and nothing of value comes up). I formally apologise if anything any words or their constituents, both vowels -and- consonants have been used previously in other posts.
Having said that now on to my question.
What is the dispersion variable modeled after? I'm trying to make a rifle that is represented as accurately as possible in terms of munition ballistics and the only data I have to model this after is target groups at certain ranges. What is the dispersion variable measured in? and at what range (if any) is the dispersion supposed to be representative of?
I've asked around in other message boards (including OFPEC). And I haven't gotten an answer yet. Does anyone here know? Info would be greatly appreciated.
