Yeah, what HE said!

Find a rifle that shoulders just as if you were pointing your finger when you played "Cops & Robbers" as a kid. Go to a store with as many different brands as possible, given your location, then fondle them all! Find therifle that speaks to you, then flip a coin between the 2 calibers.

When you're done, GO SHOOT THE THING! A LOT!

Whatever you do, don't spend too much time on sites like this: they'll talk you out of a perfectly rational & well-thought-out decision! Rest assured that you're on the right track.
