RE: Weight vs. Power
Get either one but forget about trying to get a featherweight ....get a rifle that is balanced well and a little bit on the non-hefty side. Just make sure you get a quality sling and get no longer a barrel than you require for the velocities you need. A super light wieght rifle in either of those calibers will be somewhat uncomfortable at the range and could quickly cause some bad shooting habits. A moderately trimmed rifle is fine. Balance is an important part of the package. Honestly...you'd probably be able to trim a couple pounds by just being careful about the clothing your wear and/or carry and the gear you tote along.
