It was just really bad timing. I spent most of the time freaking out over grades, thinking about all the studying time I was missing out. I was either gonna walk out of that semester expelled for poor grades or with my 2 year degree and I had a huge math test the next week so there was a lot of pressure. We also never saw anything. There was nothing really about the gun that made things worse.Literally anything the people above have mentioned will kill a deer. My question for you is what did you not like about hunting last time? Was it the weight of carrying the rifle around for an hour, was it the recoil, were you just board?
Depending on what you want from your experience there are rounds with less recoil, rounds that shoot flatter, rounds that can help you reach out and touch a deer at extreme distances. All of these answers are just fine but they don't necessarily answer your question because none of us know why you didn't like it last time.
I was also just really poorly prepared, didn't have any snacks, wasn't dressed warm enough for the early morning or cool enough for the afternoon, and wasn't in layers.
