Ths, you need to call NCSU and ask for money back for 6 credit hours if you think you can kill a deer with the same more damage at 75 yards with 00. The bead alone would cover up the whole front of the deer.

I used 00 for one trip and never again. It was when I first moved to a shotgun state, and was sika deer hunting on the eastern shore of MD. I hit a sika broadsided at 40 yards, and it kept trucking until I finally hit it again with a slugger on the second shot. Later while butchering, those 00 didn't penetrate well at all. Only a few made it to the lungs and none damaged the heart. The slug of course penetrated both lungs and clipped the top of the heart. After talking to several other butchers over there, they concurred that it was a poor choice past 35 yards. Thank goodness I had a slug for a second shot or I would have had to get the canoe out when that deer made it to the swamp. And past 30 yards, you are taking a heck of a chance of messing up the oh precious tendeloins.
