when i was a kid a family up the road hunted with 22 caliber rifles and killed more deer than most of the posters here combined .This was late 50s in catskills now i am not condoning this practice just stating what i saw and heard and bullet placement was what killed these deer no KNOCKDOWN POWER no matter what you shoot accuracy is what counts ! you can debate all night and day about energy and downrange ballistics but in the end it is accuracy of shot placement that kills deer ...
