I was using my hunting tips but I was spending to much money getting new broad heads because they got dull after shooting into target. Started using target tips. I decided to not hunt again until I can figure out my problem. I can go the target pretty good with the target tips though
You can sharpen broadheads...
Maybe I read it wrong but did you say you missed a few deer so you adjusted your sights but never practiced again to see if that was even a solution before hunting again?
You need to get to a good bow shop with a range and get someone to help you fine tune your bow.
