[QUOTE="Mike Matteson, post: 2559755, member: 101791"] You can make them from 26/06, 270, 7mm, 30/06 and few others cases. So you don't have to stay with one caliber. It was at the time I was going to have a 6mm/06 built. I became aware of the difference between the standard 06 cases, and the 280AI case. I do have a fair amount of Peterson 280AI cases presently (500) or so. I will go back in and get another 500 sometime later on. In the last year or so, I have determine that when I purchase brass I should get in 500 lots anymore. That way you are mostly dealing with the same lot of brass. I have resized brass to a different caliber for a long time. The 280AI gave me a little run of my money, but have that down petty pat now. It takes me 4 steps to size the .284 to .243 with bushing dies. The only thing is if you are using new brass. You should cut all your cases to same length first. If you cut for neck thickness, that would be your next step. That makes the stopping at the same place or point on all the brass. Cutting the brass to thickness, I have been told to make those cut in two steps, because of the thickness of Petersons Brass to start with. From what I understand the new cases are uniformed on the I.D. and any uneven thickness are to the outside of the neck. Then size to caliber. I know they say here that use a mandrel to push the unevenness to the outside of the neck, that way the bullets going in straighter. I personal don't see the gain in that. The uneven neck is still causes problem at the time of firing the case, because the uneven neck hit the chamber, and pushes the bullet out of line anyway. So I feel no real gain there. I could be wrong, but that my way of thinking presently, and that can be changed if somebody comes up with a better reasons. I will state it again, I have learn a lot here at Long Range Hunting, still do. [/QUOTE]
