Thanks to all for the congratulations. I have only ever recovered one other Shockwave and it mushroomed perfectly. I would have thought this result may have been more typical if the shot contacted heavy bone. I did use a bowhunting shot rather then a breakdown shot. Damage was great, but I litterally had to search with my finger to find the entrance and exit holes in the hide.
Either way, the backstraps and heart were delicious.
Happy New Year!!!!
