Sounds like a bad (crooked?) chamber or barrel. I know Kimber had a lot of issues with 7mm barrels and stopped production of all 7mm rifles for a long while.
I find factory ammo isn't the best way to evaluate a rifle. It may have liked a 140gr bullet, but not the factory powder or primer.
I usually start with a midweight bullet and work with it until I see some results. Jumping around to different bullets and weights is almost like chasing your tail.
