I was wondering what rifle you were using, but now that you mention it, optics and ammo can help or hinder. Okay so you use yellow box wolf, yugo M67, Winchester or PPU; iron sights and....
Ahh...wolf when I can find it, but have a decent stash of M67, it is far more accurate in my experience...1.5 Moa out of my romy kit build...wolf hovers about 3moa for me
