Looking for more of a challenge in hunting small game and was wondering if anyone else hunts with a pellet/BB gun. If so what caliber and make. I am having trouble deciding between .177 and .22 caliber for the air rifle. The .177 provides more velocity out of most rifles, however the .22 provides more down range energy. I guess it is the old arguement of velocity vs. energy, and I am sorry to bring it up again, but I feel one over the other may really make more of a difference in these lighter weight projectiles. I am not looking at dropping a lot of money into the sport, maybe $75. Will probably buy something at wal-mart or bass pro shop.
