RE: what constitutes a nontypical buck
At one time there used to be a "rule-of-thumb" of 10% - meaning ifthe final score was increased by 10% if it was measured as a non-typical, then it went into the NT ranks. This, however, went by the boards long ago.
Today its up to the owner to decide where it should be entered. Personally, I prefer typicals over NTs, so if I had a rack that qualified under both standards, I'd enter it as a typical.
