I have a Marlin 336 in .35 Rem. I have been using it to hunt deer since the first time my father took me when I was in 6th Grade (12 years old or thereabouts). Recoil is not bad, you can always put a quality recoil pad on it if it kicks too much for your son's liking. I have killed many a deer with it, never had one go more than 10 yards after getting shot. Longest shot I ever made was about 125 yards, deer was broadside to me, standing still grazing, had a nice solid gunrest on the stand. She dressed out at 140 lbs., and dropped where she stood. Shot thru some very light brush (drinking straw sized vines hanging from tree branches). Had a scope on it for about 15 years, changed hunting property to where I won't be making any shots over 75 yards (mostly 25-50), so I changed to a receiver peep sight. Brass is readily available thru some catalogs, but also tons of it on eBay. I don't use it much anymore since I now hunt in a shotgun only area for 99% of my hunting, so I have decided not to do any serious reloading for it. Gonna load up some light pistol bullet loads for plinking, but don't plan to do a whole lot of it. I have somewhere around 1000 pieces of brass, so if anyone needs some, I will sell it to you.
