That's the thing about diagnosing accuracy issues over the internet. We don't know the condition of the bore, the concentricity of the loaded ammo- ability of the dies to create straight cartridges, the solidity of the rest/bench (and the consistent placing of the gun thereon), veracity of the sights/scope, or the shooter's innate ability to shoot. (Not pointing fingers, that's a general observation.) The best we can manage is advice based upon our own experiences/equipment, and seldom does that transfer from person to another.
