.308 with light loads can be a decent varmit rifle. It is also 7.62 x 51 NATO. So you can get surplus ammo for practice. In Alabama you can't hunt with surplus ammo, only practice. .308 is more expensive than .223, but if you ever decide you want to deer hunt where rifles are allowed, it gives you that option. So you have to buy the mushrooming ammo for hunting. Don't know about your NY laws. My first big game rifle was a 30-06. When I turned 18, I bought a Browning Auto 5 shotgun. Then I bought a .30-06 JC Penny rifle, then a Marlin Model 60 .22 Rifle. This covered all bases I thought. Now I have 7 rifles, 3 .22 rifles, 3 shotguns, 3 centerfire pistols and a .22 pistol. I bought about 1 gun every couple of years to get mine. I still want about 10 more. Got a big safe to put them in. Got into reloading, sporting clays, etc. Expensive hobby. One year I got 6 deer though, had meat for a year.
