[QUOTE="Mikecr, post: 428459, member: 1521"] Yes For turning, expansion needs to result in a close match to the turning mandrel. I ditched K&M turning because this operation left me with necks that had to be sized down afterward for loading(their mandrel diameter is too large). It's not a big deal in itself, but then their 'expandiron' wouldn't be right for me either(expand too much). I've yet to run into any surprises with turning. Measured brass thickness, thickness variance, bullet diameters, turning amount, & loaded neck diameters.. All work out as mathmatical. The variance Woods sees with IDs of bushing sized necks isn't surprising as the final operation of neck sizing is not yet completed(EXPANSION). For those interested in JLC dies, here's a brochure: [url]http://www.6mmbr.com/CarstensenJLC01.html[/url] There was a brief discussion about bolt click that Boyd summed up nicely here: [url]http://benchrest.com/showthread.php?71627-quot-Bolt-Click-quot&p=597321#post597321[/url] Bolt click(popping extraction) is a problem competitors run into that is a top irritant because it mangles their runs. They're combating this specific problem(which they are directly causing) with misplaced notions that are long extinct.. Their problem AND solution is excess pressure. I say it's both, because they currently need high pressures to be competitve(in 6PPC), and of course there is a price for it. Neither greater sizing nor greater clearances will escape the results of this root cause. But this is their bubble. Their tiny little world. We don't have to run extreme pressures.
