If it doesn't fit stop. Forcing something never makes it better and often a whole lot worse.

Buddy of mine had the exact same problem. Factory ammo, brand new rifle, first range trip and bolt closing was tough. His was a 22-250. Tried 3 different types of ammo at Scheels after never firing it. That's where he got it the week before. The same ammo that wouldnt fit at the range didnt have a problem clambering in the back of Scheels. Turns out the gun just has an usually stiff bolt feed and close. The gun is a true factory tack driver too.
As I type this it just sounds weird and concerning but pressure signs haven't existed with it either and I agree if you have to truly force the bolt to get it to close, have it inspected.

Does the fired Nosler brass allow the bolt to be closed. EBay has cameras for 12.00 to 30 bucks connect to a,pc or android phone . Factory ammo should work no matter. call or take the rifle back to the dealer. could be a manufacture problem. Throat to short, if the ammo fits in the magazine it should chamber length wise. Call the dealer or take it back.

If Google translated this correctly then no the room was not cleaned...I was shooting outside dirt and leaves and bugs and mold everywhere.
But the chamber looked alright, didnt actually run a patch through it. Going to do that today. Pulling the stock to try and get a better look inside.

This is actually very likely. Since 2 different hornady rounds chambered fine. I am leaning towards thinking the Nosler was just max tolerance in a minimum tolerance chamber, and the bearing surface on the Nosler is much longer than the that of the hornady bullets were.
Or a burr...maybe the $10 ebay camera is in order

Definitely agree, that's why I chose not to fire, or to force it multiple times. Without knowing the cause of the issue it would have been foolish to keep messing with those particular rounds. I was grateful that I had different factory ammo show up that I was able to test fit in the chamber and pleased that it cycled flawlessly.

If the picture is accurate & the bases of the two cartridges are Even ? Is the one on the right the one that chambered?? But was tight?? Did it extract with relative ease??
It appears that the shoulder is pushed back & the bullets definitely jammed into the lands —-
If chamber & all is clean,
And it were Me!! I would seat the bullet deeper (enuff so that the Channellure is almost completely obscured by the mouth of case) and see if it will make Bolt closing smooth & easy - !!! If Yes - Good, if Not - contact Manufacturer or seller to take back rifle -
Bolt operation/closure & opening for extraction should be Easy & Smooth - if not dere is truly a problem

If other ammo feed smoothly - likely bullet ogive as noted earlier — seating deeper should do the trick

I have a new Bergara. Did your new Nosler round fit the DBM. If not then I can see why you were jammed. I currently am loading the Nosler 142gr ABLR and there is .073" difference between just touching the lands and fitting the DBM.
Most 6.5s have crazy long throats to accommodate heavy high BC bullets. I don't need or want to use heavy bullets. Unfortunately, the long throat means that light bullets won't reach the brass neck when set to just short of touching the lands So when I built my 6.5, I ordered a reamer with a short throat, a no-turn neck, and a barrel with a long twist. This is all ok because I hand load. But it also means I cannot use factory ammo. My barrel is not marked to identify that but if I ever sold it, I would mark it first.
I'll bet bergara designed that rifle for light ammo, and Nosler designed the ammo for long throats. Sammi standards for minimum chamber and maximum cartridge are designed to avoid this conflict, but custom rifles don't often adhere to Sammi standards.
That's just a guess.
Measure the throat and the Nosler ammo and compare. Also measure the twist. 8" is pretty standard for the 6.5. 9" or more would indicate it was designed specifically for light ammo.
Also, look on the barrel for info regarding twist and throat. Also look in the info that came with the rifle.

I recently had a similar problem with Nosler brass and discovered an inconsistent rim thickness causing tight chambering.
Another silly thought. I was reading your posts in this thread and noticed that you said the marks on the bullet were only on one side of the bullet. That's really wierd!
It suggests that bergara chambered the rifle off center (impossible to believe), or there is something in the chamber or throat that is pushing the cartridge off side (much easier to believe). You say this is the first time you ever shot the rifle. Did you clean it first? Manufacturers and gunsmith often put heavy packing grease in bores and chambers to prevent them from corroding in shipment and storage. If you didn't clean it properly, that might explain everything.... .
