I didnt see how old you are but you seem like you are a very wise fellow already. You have gotten soem greta advice from the jury I really like what Nomercy448 and a few others had said. My 2 cents worth is if money is a concern then start with a 12 gauge it is very versitile, whether it be smallgame,trap,waterfowl or deer. And if I were to recommend a rifle it would have to be the old 30-06 also very veristile, from deer to elk and bear. Shot shells and rounds for both are very common and easy to find. As far as what model thats self preference but as Nomercy said a pump would be a great start.There is so much out there to learn from these days especially the videos. I was lucky, born on a dairy farm and a hunting crazy families both sides, I had no choice ! LOL Take in a local outdoor show with outfitters and retailers and dont be afraid to ask.
