Thread: 6mm creedmoor criterion pre fit issues

hi

Just wondering if anyone has had any issues with these ?

i have a rem 660 which i got a gunsmith to fit one of these barrels (was second hand) but looked to be in near new condition. the rem 700 action it was removed from had apparently fired the factory ammo used below.

first issue went to fire some factory ammo and wouldn't even chamber (hard in the lands with a short throat) seemed odd as had been fitted up by gunsmith and one would assume they would check rifle is sammi spec, i had offered to leave brass, projectiles etc with him but he said it wasn't necessary. So after taking back to smith he puts a throat reamer up so it will now chamber Sammi ammo (and charged extra for the work), but this brings on another issue.

Next issue, apparently it has a tight neck and im likely going to have to neck turn my brass (nosler) hornady brass will be ok as thinner apparently. anyone had any pressure issues using nosler brass in these barrels?

these barrels seem to have a good rep so seems odd they wouldn't chamber factory ammo and have a tight neck. Is there something the smith may have cocked up or am i unlucky?
