B2B: Accurize your Rifle: Barrel Harmonics

[YeeHaa]

Back 2 Basics, vibrations & harmonics

So, you believe your scope ( if using one ) is no good because you can't get consistent groups? The following will briefly explain another very important variable.

For any shooter that is or has been frustrated with obtaining a "Good group" from your Liberty Sticks, the following is very good info and easy to understand.

Below are methods talked about to "Tune" your rifle in.

1) Store bought ammo
2) Changing point of contact on barrel
3) Limb saver
4) Reloading your own ammo

Not discussed,

5) Muzzle devices attached to end of barrel
6) I'm sure there are a few others, but you get the idea.

Good stuff. I skimmed through, what are common frequencies? In slo-mo vids a lot of barrel flex can be observed, thus a very low Hz. If that’s the case it doesn’t seem the small changes would make much difference due to bullet velocity. Yet they do.
