I hunt western game, in western states, cause I live here, & I would not go with a scope I couldn't turn down in the thick & nasty country, or turn up in the open country often in the same day.
If its strictly on a LR only rig why wouldn't you want more than 6x? If you hunted here, there, & everywhere you find critters why not be able to turn it down?
To each thier own I guess, but if ounces count that much I'd buy a featherweight rifle, trade the bic lighter in for paper matches, don't cary any water, or rope, cause you can drink out of a creek, & braid sinew or vines, or, just stay in the pickup.
In short, it just wouldn't do for my style of anywhere, any time any critter in North America hunting. I gotta cover country of all types.
Then again I'm "far from an expert" as mentioned in your earlier post.....
