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.
