Two Ruger 10/22s bought at the same time. They are 5 numbers apart in serial numbers. One by myself and the other by my brother.
One was broken in by the "classic" barrel break in and the other was just shot until it needed cleaning.
One year latter one will shoot under 1 inch groups all day long at 50yds and the other struggles to make 2 inch groups with the same ammo. With both being shot by the same shooter.
Guess what one shoots the 1 inch groups.
Maybe it's a myth but it doesn't hurt
As a life member and a barrel maker of long standing be assured I will call them on this BS!!! I can say that there are enough
barrels ruined by ignorance without encouraging the masses to commit mechanical suicide with such BS
The surface finish
of a barrel is a delicate thing with more of them being ruined with a cleaning rod in the hands of someone who doesn't know how to use one. I would
never in a million years buy a used rifle now because you well may buy one that has been improved.
