Good for you. You put in the work and skills to build a shooter. Congrats! I know and accept my limitations when it comes to gunsmith work.
What action are you using? You are saving close to a lb. with 22" light vs. 24" Sendero I think. Seems like a lot, but that is what Proofs website states. They seem round to the pound.My 280AI is 8.25# with March 2.5-25, Remington 700, Proof Sendero Light 22", BDL, Nightforce UL rings, Mesa Altitude.
What projectiles do you want to use and which of those would you like to "optimize" around?Primarily whitetail and anywhere between 10 and 500+ yds depending on where I go. I dont lock into only one style of hunting. I may put a tree stand on my back and haul it in a couple of miles or hike into a clear cut where shots can stretch it out. Hopefully will get a chance to get out into the Rocky Mountains before I'm too old to climb up those mountains.
Nice rifle. Friend of mine has one. Shoots incredibly well.One of my favorite lightweight rifles is a Browning 'Micro-Medallion' in 284 Win, 20" barrel. I may even take it elk hunting next time. Besides weight, I'm content with a shorter barrel with extended carry.
