[QUOTE="bigedp51, post: 1374528, member: 28965"] At the Whidden custom die website they tell you they get the most concentric cases with non-bushing full length dies. Bushing dies work best with custom tight neck chambers and neck turned brass. The bushing floats inside the die and can move from side to side and even tilt. And when reducing the neck diameter .004 or more it will induce neck runout. Meaning with a standard SAAMI chamber and larger neck diameter a bush die "may" not be the best choice. And this is why the Lee collet die is used by many shooters, not because the die is cheaper, but because this die produces less neck runout. If you remove the expander from a full length die and size the case it will be as concentric as it ever will be. But if the expander is locked down off center, or if the case neck has unequal neck thickness this can cause case neck runout. The dies expander is not the end of the world as many reloaders think. If the expander spindle is locked down straight and the "inside" of the case neck is lubed this lessons the friction and stress on the case neck. Also at the Whidden website they sell expander kits with 5 expanders from bullet diameter to .004 under bullet diameter to control neck tension. Bottom line I get the least amount of neck runout with Forster full length benchrest dies and the most neck runout with bushing dies with off the shelf factory rifles with SAAMI chambers. I personally think too much of what benchrest shooters do with their custom rifles carries down to the average reloader and is not needed.
