Thread: Barrels and Accuracy

Yeah, some good ideas there. I especially like #1

1 - if the barrel's dimensions change (as when it is shortened), then the vibrating frequency does change. You might then have to change the ammo you use as the barrel harmonics will be different and therefore accuracy will be different.

But then you should be able to get accuracy back with different reloads even after a barrel chop (whereas sometimes you can't... 'your Murphy law').
But maybe harmonics only matter when shooting factory ammunition as handloading allows you to tune a load to a barrel's harmonics?
