Back to the gun thing, I think ammo makes a huge difference. I picked up a .243 99 Savage a few years back but did not want to reload for it. I bought a box each of the "Big three" and headed to the range. The Winchester and Federal I could not get better than 6" at 100 yards. The Winchester and Federal also extracted kind of "Stickey", a sign of a hot load. The Remington was right in there and extracted smooth as could be. Lots of things affect shooting. I usually take along a rifle that I know is dead nut when I go to the range. That way I can check if I am having a bad day or it may be the rifle.
