Even with that tall front sight it shoots high? Can you try another choke tube to make sure that isn't it? I've got one barrel that I want to bend too. It shoots low, but not that much. Maybe 1 foot low at 40 yards, so little stock fit can over come it. I tried to bend it once by the redneck method of sticking it in a hitch receiver. I pulled on it pretty good, to where I was scared, and it didn't move it one bit. I've seen where people have built elaborate barrel bending jigs, and they all seem to end up with the same thing. A pipe bender, and the only way to do it is by feel and testing.
