[QUOTE="abrian, post: 977551, member: 46018"] Just finished building a new STW, im in a huge time crunch for a coveted Oregon antelope hunt in 10 days. I'm having trouble figuring out what the deal is and hoping someone can see something I'm not. Rig: Remington 700 7mm STW with Pacnor 26" barrel 1:9 twist, Vais brake, McMillan Game scout stock, Jewell trigger, Nightforce NXS 5-22, Nightforce rings and rail. The best powder/ammo combo is 73gr H4831 with Barnes 168gr LRX PROBLEM: at 100 yards I can shoot 4 out of 5 rounds 1/2 MOA, but 1 out of 5 is always a flier at least 2 inches off the group. All velocities are close to each other. Barrel is clean each time I shoot a new 5 set. No rhyme or reason on which shot is the flier either. ATTEMPTED FIXES: different powders(retumbo, h1000, & RL22), charges, bullets, different shooter, different rest, fowled barrel, factory ammo, checked tightness of rings and bases, checked action screws, barrel is bedded and floated, no over-pressure signs. Am I missing something obvious? I can't seem to shoot a group without having an unexplained flier. I didn't spend the time and money to build this thing to have to worry about a flier. Again I'm in a time crunch to use this thing in 10 days, yes I have other options, but I want to figure this gun out. Thoughts? [/QUOTE]
