I normally shoot rimfire or service rifle, but am considering getting a bolt gun in .223 remington. I already load .223 for my service rifles, but this rifle will be used primarily for paper punching from the bench at 100-300yds. Am not sure what twist to look for in the barrel, my service rifles are 1 in 8 but I doubt I will need to shoot 80 grain bullets from this gun. I had a Savage model 12 VLP in .223 a while back, it wasn't bad, but wasn't anything special either. I've been looking at the Remington 700's and XR-100's but got to shoot a buddies Cooper 21 Varment the other day, and really liked it, and am now kind of leaning in that direction. Any advice or suggestions appreciated.
