parted the hair on the top of his head this morning. my yode was about 175 yards out and was not going to come any closer. i waited till he was holding his head still to take the shot. not as hard shot unless your rifle is sighted in 2" high at 100 yards. (17 Mach IV) the 20 gr vmax is traveling at 4089 fps, middle of the head shot leaves little room for error. with the bullet climbing to 2.75" high at 175 yds it just parted his hair. needless to say i am out of practice and i will lower the poi to 1.25" at 100.
