My rifle is a Weatherby Vanguard Sub-MOA in .308 Win with a 22 inch barrel (1 in 10 twist). I've been reloading for this rifle for about 6 months now with decent results out to 300 yards (1/2 MOA if I do my part) I'm using Nosler brass, 175 gr Sierra Match Kings, Fed Match primers and 42.7 gr of IMR 4895. Soon however I intend to shoot this rifle out to 800 yards and participate in some long range matches with my local club. My question is regarding what kinds of muzzle velocities should I be getting out of this barrel to effectively shoot at these longer ranges. I realize that a 22 inch barrel isn't what most people would consider ideal for 800+ yard shooting with a .308, but it's what I have at the moment. Right now with my loads, I'm getting around 2590 fps muzzle velocity. Just curious if some of you more experienced shooters think this is adequate to send a 175gr bullet out to those ranges with a 22 in. barrel.
