[QUOTE="DUSTY NOGGIN, post: 1662036, member: 89550"] try to quit thinking of em both at thirty cal the expander button in your die is probably in the .302ish range or whatever ( all die mfgs have an idea what will cover every scenario of brass ) .. but the pilot for your neck turning lathe is different diameter .. usual the brass right out of the sizing dies wont fit over the pilot for the neck turner . so you need the expander mandrel that matches (maybe+.001) the pilot of your turning lathe tool , so when turning, it turns tight but smoothly over the pilot without any friction .once brass has all been turned then you use bushing die to size the neck down 2to3 thou less than bullet diameter .. this is when you find out what bushing you really needed .. depends on how much you took off the diameter of the neck some people add a step here run a 306 diameter expander mandrel. which'll give the 2 thou less when seating the 308 bullet good news is you only need to go through this once and you are gonna be amazed at how evenly and consistent the bullets seat after this ..
