Hi everyone. I got a Thompson Center Triumph Bone Collector for my 40th birthday, this past summer. I've only bow hunted before this year, and took a decent 8pt earlier this month. In Indiana, we only get one buck tag, so I decided to go out on Saturday and try to get a nice doe with my new gun. I have taken 30 practice shots to get it sighted in at 50 and 100 yards, and have gotten very comfortable with shooting it. My bullet was a T/C 250gr shockwave with super glide sabot, and I was using 100gr of fff pellets (2). We saw 17 deer that morning, and I was finally presented with a 52 yard broadside shot at a very big, mature doe. There were 6 deer in this group, and after I took the shot, it was a full 2 count before they reacted and I watched my deer gracefully bound away, flagging her tail. I spent the next two hours second guessing myself. How could I have missed at that range? I eventually got down and went to look for blood at the site of the shot. There was none. I walked 30 yards to a fallen tree that I had seen them jump, no blood. 20 yards further on, it looks like someone rolled out the red carpet, and I found my doe another 40 yards down the blood trail. Being a bowhunter, I put the bullet exactly where I would put the arrow. I punched right through the center of both lungs. The exit hole was no larger than the entry hole. In hindsight, and going forward, should I just aim to take out the shoulders, or is there a better bullet/powder combination that will be more effective on a lung shot. I don't want to ruin shoulder meat if I don't have to, but I also don't want to risk losing a deer on what should be a perfect shot.
