My 18 yr old son says Dad's Winchester model 70 7mm is "too big," and he'd like to get a .22 of his own. This is the first time he's expressed an interest in shooting. His usual hobby is being a moderator on an auto forum. (Dad is not a hunter, his answer when I asked why he doesn't practice with his rifle or 9 mm Hi-Point: "Don't need to, I hit what I shoot." Gotta love him.) I'm not familiar with rifles, except for the M16A1 but that was 22 yrs ago. Any advice is welcome and appreciated.
