I dont have or shot the caliber your talking bout.It sounds like to me you come from a hunting family so i would ask dad to let you advance to a higher caliber.maybe 270 or something like that.Im an old fashioned guy and the minimum cal is 30/30 most likely a marlin lever.Whatever you choose remember this .you are supposed to be confident in your abilities to kill the deer quickly and humanly.Remember the snipers motto "One shot one kill".I would approach dad and ask him to spend some time at the range together,you may not realize it now but in the distant future you'll look back as these times and be happy.Oh to be young again.excuse me i got a little hallmark/sappy on ya.But i'll say this I'll never forget the time my dad taught me how to shoot .It was like i joined some special club,.
Now therefore take, I pray thee, thy weapons, thy quiver and thy bow, and go out to the field, and take me some venison.
Genesis 27:3 "The thinking deer hunter should mature through three phases during his hunting life. First phase, "I need to kill a deer." Second phase, I want to harvest a nice deer. And last phase, we must manage this resource so our children and their children can experience the grand tradition of good deer hunting." - Jim Slinsky
