If you're packing in on a horse, then I wouldn't worry about the weight of the rifle at all. I also wouldn't even worry about getting a new gun. If you're going to do DIY backcountry, then 100 percent find the happy medium of lightweight and recoil. Light guns are amazing to carry, but suck to shoot when you get to the top end of the 30 cals. I personally don't believe in brakes...if it's hitting that hard to where you can't shoot it, then find something else to shoot in my opinion. My two rifles are the Kimber Hunter 6.5 and Remington AWR 30-06. If i'm going to be going further than four miles, then the Kimber is the gun i ALWAYS pick because to me the extra 3 lbs does become noticeable after a while. If you're going to go lightweight, then leave the big 50MM scope off of the gun because it honestly defeats the purpose of spending so much money on a "lightweight" rifle IMO. Ounces turn into LBS, and LBS turn into pain after so many miles. Everyone elses input has been pretty spot on. Best of luck.
