[QUOTE="AZShooter, post: 1124618, member: 5219"] Kevin and Bigedp51 mentioned an important issue that needs to be explained in detail. Many brands of brass have varying neck thicknesses. Lapua, RWS and perhaps some Norma are the exceptions. If a bushing die is used with brass that has different wall thicknesses the OD will be the same but the ID will vary. This will affect neck tension. Kevin's method of using a bushing die to ever so slightly reduce OD then running it past a sizer ball is a great idea. It is far less harsh than using a conventional FL sizer die with a expander ball. The standard FL die is setup to reduce the neck OD on any brand of brass regardless of neck wall thickness. In some instances this can over work the brass. A friend used his S bushing die to size all his Remington 338 RUM brass. He set up the rifle to shoot the 300 gr SMK so the bullet engaged the rifling. Two of his cases left the bullet in the bore when he removed the round!!!! Those two cases had the thinnest necks so they had very little neck tension. IMO you should use a bushing with brass having the same neck wall thickness. Either turn the brass or stick with a FL die with expander ball OR use Kevin's method of a bushing die in conjunction with a sizer ball. [/QUOTE]
