i have a DPMS 16" barrel 1-9 twist.. So would it be ok to hunt mid-size game such as white tail deer? Yes, i know... I should use the bigger calibers, but since WI allows .22 caliber center fire, I want to try it. Any ammo recommendation? I looked at the Hornaday 55grain vmax and they might drop a 125-150lb white tail with a neck shot.. Possible?
