[QUOTE="bigedp51, post: 1298590, member: 28965"] I have a Forster bushing bump die and several other type neck sizing dies. And as stated above the body of the case is not fully supported as it would be in a full length sizing die, meaning more neck runout. Also when using bushing dies if the neck diameter is reduced .004 or more you can induce neck runout. Meaning in a off the shelf factory SAAMI chamber a bushing die has a high probability of having more neck runout than a non-bushing full length die. And at the Whidden custom die website they tell you they get the most concentric cases using non-bushing full length dies. I get the least neck runout when using Forster full length benchrest dies with their high mounted floating expander.

I never understood why Redding used a oblong expander that even when the inside of the neck is lubed creates so much drag and pull on the case neck. [IMG]http://i.imgur.com/kWbieba.jpg[/IMG] [/QUOTE]
