[QUOTE="Alibiiv, post: 1575391, member: 69192"] You're a little ahead of me with the process, however will take a shot at it. The .270 Ackley Improved is what I am having built. The parent case (.270 Winchester) is the same length as the .270AI case. I have some .270 Winchester ammunition that I intend to pull the bullets off of. I intend to anneal the brass, then reload this brass (with the pulled bullets) with a mild load to fire-form the annealed brass. I am pretty sure that with this Traditional/Wildcat chambering I ought to be able to just shoot them in the new chamber. There's another way that I've read about with a light load of "Bullseye" powder and cream of wheat, but..............I do not know the exact process. I'm sure that if you search the forums on here you'll be able to find out how it is done. I've also thought of opening up the .270 brass with a 30 caliber expander, resize the brass back down with the .270 Winchester resizing die that has been backed out to create a false shoulder to the dimensions of the .270 AI chamber; where the neck meets the shoulder. The last process that I have read about is to load the parent case with a mild load, however back the seating die out so that the bullet engages the rifling so that it holds the base of the case against the bolt face. I've fireformed .308 Winchesters to .358 Winchesters by simply chambering the round and firing it. I've lost some casings due to splitting, however I was hard up for brass and that is what I did. Loading for a wildcat is totally new territory for me, thus my opening sentence on this post. Before I try any of the methods that I have written about I intend to research it a bit further. I had a .358 Norma mag many many years ago; dinosaurs had just been put on the protected species list. I used to fireform the brass out of 7mm Remington brass (2.500 case length). I found dimensions for the .338 Norma Magnum to be 2.492, 7mm RemMag ought to work for you. I can only suggest that you search these forums to get other's opinions with your question.
