What rifle to use
So, we just moved in June to this property that has boucoup deer but we've never hunted before. I suck at marksmanship so I'm asking my 14 year old son to bag us a buck this fall. He has a much steadier hand (plus, I would rather he got the bragging rights). He has a J.C. Higgins bolt action 22 that we pling with and that my father and I plinged with in or about 1963. It will take 22 short, long, and LR: but not magnum.
I never thought that you would use this rifle to hunt white tails. But the first place I looked online to get advice, Remington.com, under the rimfire section, has a 22 rifle that includes the term "big game" under the description.
Can you really hunt white tail with a 22? If not, what ammo would you recommend for a novice hunter at close range? He would be in a tree stand within 50 yards of his quarry.
