[QUOTE="J E Custom, post: 1655984, member: 2736"] Sizing brass from one case to another is not an uncommon practice, But when you don't have to it is better all round. It will have the correct case and neck thickness. If you size down the case wall will thicken. if you size up the case wall will experience thinning. If you thin a neck wall by sizing up, it will work harden quicker because it will expand more to fit the chamber when fired. the reason for turning is to uniform the wall thickness or to give you a certain amount of clearance for tight neck chambers. So the reason to only turn enough to clean up uneven wall thickness is more even bullet grip and best fit in the chamber. Manufactures don't have a universal case that can be formed into almost any case, they form a cup with the right size and thickness to form a straight sided case then in the last steps they form the shoulder and neck and end up with the right shape, size and thickness. then they trim the neck to get the correct case length and this length is effected by how thick the neck was when it was in the final sizing. Then if we turn to much, we effect this and brass life suffers. Often when sizing down a case or the neck, we have to turn in order to get the proper clearance because the neck becomes to thick. Proper Head stamp is also a safety issue and should be utilized when possible. J E CUSTOM [/QUOTE]
