Huh!!, non linear or keith to lbt lfn design. Guess what boys if it hits where your aiming and your happy that is all that counts. If you shoot at game within the distance that is mentioned as your max range who cares about something being non-linear it's a moot point if you will never take a shoot beyond that distance. AS for Lil' Gun she gets a bad rap. If it shoots great and everything is looking good, don't worry your not going to gas cut the ole girl in half!!
