Improper charge weight can cause groups like that. I start .050 of the lands and adjust charge weight until groups tighten up. ( only with Barnes bullets ) As mentioned, seating depth does the same as well.Not uncommon to see this with a Barnes x bullet.
Just a suggestion but I usually start with a bullet that I know is easy to get shooting. The Barnes x is not difficult but not as easy as others. If the rifle won’t shoot a game king or ballistic tip there is something wrong with the rifle. These are easy to get shooting well generally.
