Lever gun for my son

My son will be 10-years-old in March and it's time for his first gun. His sister's already got a 22 rifle and 20 ga shotgun and let's him borrow one when I take him hunting. Next step will be a rifle that they/he can use for deer. I'm thinking about a 44 mag lever action rifle. I saw a used one (Winchester?) just his size in a local gun store. I figure he could start off with some 44 Special rounds and work his way up. Whaddya think? :?
