At first, I was using field points when praticing. They were 125 grains, the same as my broadheads, but I found that after I sighted in my bow and switched back to the braodheads, I shot low. I asked the guy at the pro shop about it and he said somtimes the broadheads will fly diiferent. He asked me if I was lining up my broadheads with my fletchings and I was. So I ended up sighting my bow in with my broadheads and buying a new set of broadheads to hunt with. I'm going out this morning after the deer bed down and get up in the stand and pratice from there. I think you guys were right in saying I dropped my left arm and did not bend at the waist. Anyway, thank you for all your input. I appreciate it. The last thing I want to do is wound a deer.
