Bolt won't close on bergara with factory ammo

I had either a bergara or tikka. I misremember which that had the same problem. I finally figured out I had the wrong screw in the rail. There were two lengths and the short one went up front or the bolt wouldn't close.
Talley rings....all screws were same length but definitely worth a look...and boy would I feel stupid.

No
Looking at that pic your bullet was jammed into the rifling for sure.
You've got a super short throat on that rifle.

Hmm, hadn't thought of that but I've had the same problem before. Also happens with over torqued/overly long action screws sometimes.
 
If the bolt wont close its jammed pretty good, if theres enough neck tension the bullet wont pull.
 
Ever thought about that there might be an issue with the factory ammo? The so called Delta - L problem, which means in reality that the delivered ammunition was manufactured with maximum tolerances, but your chamber has those of minimum. Happened often and is happening still.
 
Welcome to base to ogive measurements. Your throat isn't long enough for the ogive shape of that bullet. Curious what Bergara did on that rifle, as I've personally seen a dozen B14's chamber all the way up to 147gn while teaching classes.

If you push them into the case .1" it should do fine. I doubt it'll affect anything pressure wise enough to say grace over.
Wondering what your over all opinion of the Bergara is?
 
I'm out shooting right now, and the bolt wont close. Brand new bergara b-14 6.5 creedmoor, never fired. Trying factory Nosler 120 gr ballistic tips. Tried to chamber one, bolt wont close, tried another and another. Very tight. Forced it on one and drag marks on bullet. Not firing it because from what I'm seeing it looks to be jammed .250" When I get home I'll start taking measurements to see what's going on, but just from my description and the picture below what say you?
One chambered, one not.View attachment 123871
La chambre a été bien nettoyée ?
