Long range caliber recommendation

[Bart B.]

I have noticed all kinds of theory, but it doesn't seem like there is actual experience in some of these things...What do I know I am just a new guy.

Are you wanting to notice actual differences in steel tube's vibration frequencies between two different lengths but the same diameters?

Consider this stuff:

Create your own barrel profile using this site to see how the muzzle axis moves vertically.

Use a 1.2 millisecond barrel time to see the angle.
