That is a couple of nice rifles you are considering. If a little extra weight does not bother you to carry around then I would get the heavier rifle. IMO you will shoot better with the heavier rifle. You picked a couple of good cartridges. Personally I would reconsider and look at a 308 or a 30-06. Simply because ammo will be cheaper, and you will have a bit heavier caliber if you decide to hunt anything else. The 30-06 is considerably more cheaper to shoot than the two cartridges you listed(also the 308). A lot of people think the lighter cartridges are just as effective on deer as the 30-06. Personally I do not believe they are. However a lot of people consider the premium bullets necessary in the lighter caliber's. Premium bullets are not necessary in a 30 caliber, which will make ammo even that much more cheaper. Tom.
