I'll preface this by saying I'm not a hunter. I'm wanting to get started with a pretty tight budget. so any help will be greatly appreciated.

I am in the market for my first hunting rifle. I found a good deal (?) on a Ruger American .308 with a scope (I think it's a bushnell but I didn't get the model number) for $375.

I guess my question is regarding the caliber. is that a good caliber for deer or should I look at a different caliber?

and while I'm at it, does anyone have this rifle? if so, what are your thoughts for this gun?

thanks, fellas.
