RE: 7.62x39mm for deer
An sks is about like having an auto 30-30. I haven't killed a deer with it but I have hunted with it before. I just have never had a opportunity to shoot at one with it. It is not my primary weapon of choice but I would use it. My rifle will shoot tight groups out ot at least 100 yards. They are fun to shoot also, and the ammo is cheap enough you can practice alot.
n3ywv: not everyone lives in your state were semi-auto rifles are illegal. Does that go for '06's and such too? They are not fully-auto machine guns.
Dan O: I think most sks rifles hold ten rounds not just five, but it only takes one.
