So I bought this barrel that is supposed to be 1x7 chrome lined, and It's 14.5".

The problem I'm having is with accuracy. The barrel will shoot 75gn, and 55gn bullets just fine. But absolutely will NOT shoot 62gn bullets. I'm talking no less than 3" three(3) shot groups at 25m! Yes you read it right, 3" groups at 25m!!!

The 75gn bullets shoot with laser accuracy, and the 55gn bullets shoot like the 62gn bullets should.

So whats going on here? Is the barrel messed up? I want to shoot M855 through this thing, but can't because it won't shoot them. 75gn bullets are way to expensive for my taste, and I just plain don't like 55gn bullets.

Am I screwed, or what? Anyone had this happen before?

Some weapons simply favor some bullets more than others.
Try a different brand of ammo.
Try it at 100 yds. It seems counter intuitive, but some bullets do better further out.
It is a known phenomena which has been discussed on the board.
