Bad shaving in barrel

[biodsl]

Hollis...try single loading, hand feeding every shot on a few five shot groups and seeing what you get. I have a Lilja barrel that will shot five rounds touching when singled loaded but prints two distinct groups when loading from the right and left sides of a magazine. I don't pretend to understand why. I only know it's a function of the auto-loading function.

Second note: expecting a $130 barrel to shoot 4 inches at 500 yards might not be realistic.
