[QUOTE="Mike Matteson, post: 2378152, member: 101791"] I just got in 500 high in rifle cases. Found a fair amount of inconsistency in COAL. All that I checked are shorter that spec out to, which kind of bugs me. So I have taken15 cases and cut the case length to a consistence length. Getting read to cut the necks for thickness before changing the neck DIA. I came to the conclusion to cut 1 cases for thickness to see if it will chambers with the reduce neck to size required. The Smith want to check to see if everything is right on. (I agree) He wants a total of 5 cases to fire to get COAL after firing the cases. (I agree again) I had the neck chamber area reduced to be smaller than spec. So I am reducing the neck size from .284 to .243 caliber chamber. Now I am debating with myself if I am going to anneal the cases after or during that process to reduce the neck size or not. I will be stepping the brass down 3 time to achieve the required neck sizes. The only change is the neck size. The balance of the case is the same as to 280AI case dimensions except to the neck. I am looking for input. I presently have 2 sets of 280AI FL bushing dies on hand. Looking at getting a 3rd set bushing dies, so not having to change out bushing as I do the step down. The 3rd set will set to bump back to .001 to .002. So once set it will be consistence and hopefully I don't have to change those again. [/QUOTE]
