[QUOTE="uncleB, post: 96500, member: 4679"] Lerch, A percentage of this (somewhat small) can be caused by neck wall thickness varience. neck turning off the high side helps. A standard seating die can make matters worse. 90% of the problem is in the SIZING process, a standard RCBS or hornady die way oversizes your brass. example: take a fired 270 Win case and measure the neck run it through your RCBS fl die without the expander ball...... .025 smaller check your concentricity guage not bad .001 run out . now put the expander ball back in WOW .001 to .010 run out. this is where bushing dies (redding ,wilson custom come in). minimum sizing on uniform neck thickness brass and treating the expander ball like the mother in law is where the number ZERO is awesome.
