[QUOTE="Plowboy85, post: 1960725, member: 66137"] I have heard several folks mention using an expander prior to seating. What would this result in that couldn’t be accomplished without the step? The only positive I can see is a uniform ID when a die would result in a uniform OD. I, like most folks do not utilize the expander ball in my dies. I use quality dies and neck turn all my brass if needed. I prefer to have no more than +/- 0.0005” neck thickness variation around so since I try to get near uniform neck thickness I assume the post sizing ID is fairly uniform. My other question is wouldn’t we result in a very low bullet grip if we seat after the expander? All of mine (K&M) are 0.0005” under the caliber dimension. I never get tired of this forum, so much knowledge and experience can be gained....thank you all. [/QUOTE]
