I have a dilemma. I want an all-purpose AR-10 as my designated hunting rifle, a rifle I can use for all types of hunting and game. My issue is that AR-10 rifles are heavy, with the lightest I've found being the 8.2 lb. Nemo Arms and CMMG's 8.25 lb. Resolute 300. With a decent scope, I'm looking at 9.5 pounds at least, if not closer to ten pounds. My current rifle is a Savage 270 win that comes in at 7.4 pounds. My question is: is the extra 2-2.5 pounds enough to cause me to have issues holding my gun up for long periods of time in the event I'm watching an animal in the optic? The last deer I killed took a few minutes to identify as a buck through my scope. I am willing to spend the six grand on a Nemo .308 and a decent scope, I just want some feedback from educated folks about gun weight. Thanks.
