Those pellets are absolutely awesome.
I whacked a Crow a few years ago at 110 yards right off top a telephone pole across from me. Nothing but a mountain behind it.
Believe it or not it was with my Discovery that's been hot rodded and sending the 13.43's at 900+.
It hit him dead square in center of chest and he toppled end over end, DRT no flapping or nothing.
Entrance non detectable without plucking but exit was almost dime sized.
Good one OP.
