What I did, was get an old axe handle made out of Walnut and cut it down. Then I drilled out the business end and loaded it with 16 ounces of lead and sealed it up with epoxy and wrapped the handle.
It’s “Lights out!” for the poor lil’ fishies whn I bonk ‘um on their cute lil’ noggins wit it.
Big, scary sharks I shoot with my 22. Doan wanna bring in no GREEN Makos or Threshers. I gotta a friend that did this and the thing damn near destroyed their boat. Bit the Holy Chit outa their upholstery and everything! Real exciting!
Heard about some cops that did this once and then shot a hole in their boat trying to kill the darned thing.
PS: 22. caliber long rifles work best on big fish. The shock value sends them straight to the other side.
