And in PA, there are these small furry critters that screw up a pasture pretty bad, and the PA ppl I know, that hate those critters, always wanted a superfine crosshair to see critter eyeballs at distance, so the crosshair change might be normal for some older PA critter killers.
And kinda historically, b4 stadia crosshairs, the snipers who used the old unertls/lymans/early Redfield & Unertl m40 scopes, called them meat scopes.
Using them against humans standing upright, having zeroed at xx distance, they would know where in the 36" from head down to pecker, where to hold at non zero distances to hit meat, within the trajectory of their round at that specific zero.
Knowing the 36" meat chart with a couple of zeroes allowed them to make some pretty good tallies in Korea & Vietnam. This system doesn't work well when you reduce the meat range from 36" to say 18" on a big whitetail, or 9" on a big dog...
