[QUOTE="MagnumManiac, post: 554200, member: 10755"] The most accurate to way to reload your cases is to neck size, and only bump the shoulder once the brass becomes hard to chamber, which may be 4-5 firings or more. You only want to bump the shoulder .002" from the fired dimension, anymore will be giving too much headspace. In addition to the die set, you will also need a measuring device to measure base/shoulder length of your fired brass so that you can size them correctly to the right dimensions. I use, and recommend, the RCBS Precision Mic. It's user friendly and measures accurately to within .001". They are available for the RUM cartridges. The best setup is: A 3 die set that contains a FL die, Neck die and Seater die. Now, you have the option of buying a Neck die of the bushing type (recommended!), a body die (recommended!) and a competition seating die with a micrometer style adjustment for depth. This may not be necessary, a normal Seater die can work just as well if you have the correct measuring devices. I would recommend a Redding Type 'S' Match Neck die set, this is what I use for my competition 300WM rifle. If you are just making up rounds for hunting, a Redding Type 'S' Bushing die set, with the addition of a body die, would be ideal for this purpose. There is nothing wrong with a standard 3 die set, but with the bushing die you can get very consistent neck tension, which should run from .0015"-.002", anything more is not necessary, even in a hunting rifle! gun) [/QUOTE]
