how many "abnormal points" or "abnormal inches are needed in order for a buck to be considered nontypical.

I just visited the Boone & Crocket website, and couldn't find a definitive answer. Maybe there isn't a minimum. I was right about the 170 and 195 numbers though.

Lets say you had a buck that scored 180 net typical, but had 6" of non-typical growth. Wouldn't qualify as non-typical for all time, but subtract the 6" for 174, qualifyies astypical.

Same buck has 16" of non-typical growth, qualifies as non-typical (196), but NOT as typical, would only be 164.

190 net typical with up to 19" non-typical growth would qualify in either category.

For lesser bucks if there's non-typical growth, just add or subtract it to the net typical score and that's your bragging position.
