R-22 jug,and a 10" 4 bladed brass boat prop hanging from a tree @ 185 have become my Mk2 fps proving grounds -Once I found the the hold off for todays wind it was on! I used the jug to fine tune the prop,which the wind blows profile to me 1/2 the time presenting a 3x10 inch target-Its music to me- tonight with a green hog light and lit recital I,hit the jug then the prop shadow back and forth till I was giggling,actually shot the jug down,could barely contain myself after that,nailing things @185 in the dark with a pellet gun what fun! Amazing time to be part of this hobby/sport,takes all my time anyway.
