[QUOTE="blipelt, post: 811611, member: 11310"] Yawn I did a little tinkering now that my cooper NEW 280ai is back from the factory. They put a little blurp at the bottom of the repair saying "Cooper Firearms 280AI chambers are not SAAMI spec. They are chambered to the original P. O. Ackley spec. SAAMI spec ammunition may not work in a Cooper Firearm. In my explanation I put I had New Nosler Brass that wasn't ejecting and the rifle hasn't been fired. Tinkering I did. I took the firing pin assembly out of my bolt and put a new Nosler brass in and chambered it. I checked for any movement in the bolt when the brass was chambered. There was none! I removed the brass and checked you had movement! I am going to try the brass out. I might seat the bullets into the lands with a light load to see how it does. Don't want to end up ruining a bunch of brass. Having movement when fireforming brass makes really poor quality brass. Brent [/QUOTE]
