[QUOTE="azsugarbear, post: 841212, member: 4809"] What you are describing is done all the time. It is best done in steps, rather than all at once. It is easier on the brass. I shoot a 277 Allen Magnum. I start with a 338 Lapua Magnum case and run it through a Redding bushing die. I first take the case neck down from .338 to .323. Then I neck it down again to .308. I then anneal my brass again before taking it down to .284 and then, finally resizing at .277. Working the brass that much can make it hard, so annealing becomes your friend. You should watch for a thickening a brass at the neck (turning may become necessary). You also need to watch for the "doughnut" - a potential ring of brass that builds up inside the case where the neck and shoulder come together. [/QUOTE]
