So you don't believe in barrel harmonics?

Not that educated, I'm open to suggestions. I know what you mean when you say barrel harmonics but I do not know how to corr3ct.

Search "Horizontal Groups" and there are 10 pages of previous threads. Maybe you can find answers in there that might help you out. Good Luck!

Some pieces of barrel steel have internal stress.Either by over/under dense material,grain structure or internal pockets......
After you rule out youself,by letting someone else shoot gun,bedding.... get a good trigger...set low for load development..... no uneven stock pressure.... use some high quality factory loaded ammo.
Send barrel back to mfg.
