Locked up bolt with factory loads is a little troubling. Can you drop a bullet through the neck of a fired round? There are a lot of things beside powder that raise pressure. Please define locked bolt.

The bolt would not lift to eject the shell, it would move a bit but i was afraid it was gonna break. It was in the first 20 shells I shot thru the gun. I didn't have a chrono setup either. Hasn't happened again since that box of factory ammo.

Was it the Hornady or the Nosler ammo?

Hornady eld x factory loads jammed up

That would have been my guess. The case on the left in the second photo shows a ejector smudge. Slight but it shows.
So, I do not misconstrue your statement; are you saying they are loaded touching the lands?

My hand loads were by the book, I don't know what the factory was at that jammed. Just learning all this stuff new and my experience so far. I think this gun is slowly getting easier to eject n feed. I loaded them right at 3.265 and by the book but the bolt seems to go down tight so next batch correct me if I'm wrong I might kick it back to like 3.263 col ??

Take a sharpie and color the whole bullet,then chamber the round. If you're jamming it,you will see rifling marks on bullet. If not you have Interference somewhere else.

I may be misreading this but I think the OP reloads are chambering fine. I think it was the factory ammo.
As far as the bolt closing tightly, you will probably have to bump the shoulder back .002 not adjust coal by .002. Plenty of YouTube videos on how to do this if it's not covered in the manual.

I will look into bumping the shoulder back thanks
When we say jammed, most of us mean the bullet is touching the land. If you followed the book, you would likely not be touching the land, maybe .010-.020" off the land, not jammed.
You might generate more chamber pressure when bullets touch/jam into the lands.
100 fps is negligible! Check the manual...rest gun may have been 24" barrel.
Idk if it's been said but my experience with loading for 6 different Christensens is they pressure early. 4 Ridgelines and 2 ELRs. Usually about middle to just past middle of book. Velocity has been good though. Also one 6.5 PRC with factory Hornady 143 eldx would b in the lands a good ways.
Start low work up and like others said listen to what your rifle is telling you. Good luck!
