[QUOTE="rharfo, post: 811151, member: 50031"] Ok folks, I recently posted a thread that ended up with a dozen pages on the difference between the saami spec and Akley 40 degree specs of the 280 AI. Heres the new issue I am having. I bought a brand new Dakota 97 Hunter in 280 AI. Fireformed some casings. After full length resizing they will hardly go back into the chamber. During close inspection it is obvious to the naked eye that there is a difference in the fire case shoulder and the resized case. From my previous post I made it known that I confirmed with Dakota that my gun is a 40 degree pre sammi chamber. My dies are over 10 years old confirming from Redding info that they are the orginal spec 40 degree. I have emailed Dakota but its a holiday weekend. So, what is the issue. Why is the fire formed case not "fireformed"!? Is there a headspace issue? Should I buy a neck sizer die? Is the chamber not cut complete? Not sure it will show up in the pics but the case on the right is the fireformed vs the left being full length resized. You may be able to see that the fire formed is "rounded" and the resized has a sharp shoulder. Been reloading for over 10 years. I had a factory REm 700 280 rechambered to ackley with NO issues. The Dakota was VERY expensive and to have ANY issue is less then acceptable! Thanks in advance for your thoughts. [/QUOTE]
