Bear Creek rises to the top

[Sticks]

Take a factory load, drop it in the chamber, make sure that it is fully seated, muzzle up and see if the round falls out or needs assistance with a cleaning rod from the muzzle. I would take the bolt with the extractor removed and use it to make sure it goes into battery.

Short throats have been the issue with BCA. Factory ammo gets jammed into the lands. Not good at all. If it fails this basic test, either have a gunsmith ream it for another $90, or send it back, and buy an Odin or Faxon barrel.

If you reload then you hopefully know how to measure where the lands are, then you will know for sure.
