Hi all, I need some help. I am looking to build a very accurate lite and fast " Running Rifle", not a walking ,hiking, climbing, or sheep rifle but a highly accurate running varmit/target rifle. I live at the edge of a liberal town with liberal nabors and this requires me to run 1.4 miles (google earth) thruogh hills, trees, and brush to my backyard shooting range, almost 3 miles round trip 2 to 3 times a week. I have a 13 lb Surgeon .308, a 8.5 lb Rem .270 and a 9 lb Ruger 77/22 target, i am getting tired of running these boat anchors. The trees and hills limit my shooting range to 500 yards, so i was thinking of a .223 remington as light possible. I would love 5.5 lb with optic but I will run 6.0 lb if it saves me mad $$$. I can spend 3 gran on the rifle and 1.5 on the optic but hope it's less. Can you all help me?
