Every rifle I've put a can on got MORE accurate.... and easier to shoot.
You should try pulling your head out of your ass... and I bet stuff "looks" way better...
What are the physics behind better accuracy?
Just a couple of SWAG's, but I'd assume that reduced muzzle blast causes less aerodynamic upset on the base of the bullet as it exits, which means it achieves gyroscopic stability quicker and easier.
I'd also think that the dead weight on the end of the barrel acts as a harmonic buffer, decreasing the amplitude of the sine wave running up and down the barrel at the shot, so tuning your load to be in a node would be easier and less critical.
