Hello and Welcome from NE Ont. ! As to your question , start small as in a .22 , Bolt gun would be best to learn basic shooting skills , and reduce the chance of developing a flinch . Can then build , 22 auto (10/22 my personal favored} depending on your body size 12 ga or a 20 pump . Hunting and target shooting can call for different Calibers but that's for a different day ! Good luck with your journey into the addiction !
