No offense to the OP, but I tend to assume when someone is asking about a $400 rifle, from 5.56 to 308, they don't have an extensive collection, or likely ANY firearm already. Maybe a 22LR. I've been told HUNDREDS OF TIMES in the last ~20yrs, over and over, "I'm not new to firearms," and then find out a student meant by that they'd shot a 22LR with their grandpa a decade prior, or they've shot a few times with their dad's or grandpa's rifle. I use the same anecdote with these folks, "do you know Michael Jordan?" To which they always answer, "yeah." So then I ask, "What's his phone number then?" Of course, none have his phone number. "I know how to shoot." Ok, stand up and knock over my 200yrd popper out there. So for the OP, if you've been shooting some rifle every month for decades and have a fleet of rifles to choose from in your safe, then forgive my assumption. The question spanning from 5.56 to 308win for deer doesn't imply a lot of experience.
