I experienced the same thing with a Ruger Predator in 6 Creedmoor.
A predator hunting friend of mine had necked down the 6.5 Creedmoor case when it first came out to 6mm and had a rifle built for it. The cartridge quickly became a favorite of his. I decided to follow suit, but first wanted to shoot one to see how I liked the cartridge. Ruger came out with the Predator in 6 Creed so I bought one at the LGS. I ordered the same brand brass and the same 105 grain JLK bullets my friend was using for his predator hunting. I had the powder and primers on hand like he was using. After putting together test loads, I literally "strapped" a tested Leupold 3.5-10x40 scope on the rifle using the old style Weaver rings that fit the rail that came on the rifle and headed to my 100 yard range. I dry fired the rifle a few times and found that my dislike of Savage-style triggers still existed. Pull poundage was good so I bore sighted the rifle and fired a shot. It was on the target so I shot two more times. The three shots measured .181"!! I moved the crosshairs to put a bullet 2" high and fired a shot. It was 2" high so I fired two more shots. Those three measured .239"!! I shot a few more groups and all were in the .2's so I decided to install a Timney trigger in the rifle and go hunting. All shots I have taken with the rifle at deer have been one shot kills at various distances.
The moral of the story is I am still shooting the Ruger and still have not put together a custom 6 Creed. Those Rugers are darn good shooting firearms and after reading your story, my experience and reading about others who have had great luck with them, they sure seem to be worth the modest cost. Besides, I am old and love clip rifles!!
