IMO choosing a barrel length is secondary to choosing an action style, unless you have a specific need or desire to reach out to extra long distances (i.e. - pronghorn or beanfield shooting).
Are you a stand hunter, still hunter, target shooter or all 3? Woods or open spaces? The weight affects handling characteristics and while a longer barrel length may provide slightly more velocity and accuracy, the advanatges aren't always noticiable to an offhand or snap shooter, and heavier weight can promote fatigue for the still hunter.
But weight does reduce recoil and that is also desirable, but more so if hunting in a warmer weather state where the hunting clothing worn may not be as heavy to help absorb it.
A benchrest shooter may want all the weight that they can get, so then go with the heaviest laminated stock material, and don't forget to add the weight of the scope.
Sometimes the smaller caliber barrels are heavier too!
Caliber choice depends more on the size of the potential game and how flat you need the bullet to travel (big bodied deer vs. small deer, bear, elk, etc...) Sure there are sectional density and ballistic coefficients...but caliber size helps too).
I shoot with a short barrel for woods hunting and for easier handling, and I have a wood stock and scope for more weight/less recoil.
Every rifle characteristic can have an advantage and disadvantage, and that includes the price of the rifle too!
Is barrel strength really an issue for you? If it is, then buy American.
What are some of the rifles that you have in mind?
