I had a recent manufacture Ruger K1B rebarreled to 358 Win and used the Hornady 200 round nose to take a 10 point whitetail in OK this past season using TAC powder but I don't recall the charge weight. It was a high shoulder shot at close range and dropped it like a stone. It was my first use of any Hornady bullet to take game and given the short range of under 50 yards is probably not a definitive testimonial. Nevertheless, it worked perfectly and I won't hesitate to use it again.
