[QUOTE="bigedp51, post: 1337594, member: 28965"] Your die might be pushing the shoulder back "more" than the + .010 competition shell holder. meaning you may need .012 or more air space gap between the shell holder and the bottom of the die. Below start with a .020 feeler gauge between the shell holder and die and size a fired case and see if it chambers. If the bolt does not close then use a .018 and thinner until the bolt closes. If the bolt closes with the .020 feeler gauge then you will need to go thicker. [IMG]http://i.imgur.com/7FfXhJ7.jpg[/IMG] Before I got the competition shell holders I used the Skip shim kit that you could stack and have more than .010 setback for less shoulder bump. Before that I used feeler gauges like pictured above for less houlder bump. [SIZE=4]Skip's die shim kit [URL]http://www.sinclairintl.com/reloading-equipment/reloading-dies/replacement-parts-amp-upgrades/skip-s-die-shim-kit-7-8-14--prod33197.aspx[/URL] Bottom line many dies for rimmed and belted cases push the case shoulder back more than you would think was needed. And where a Hornady cartridge case headspace gauge comes in handy to measure your fired cases and adjust the die. Below a fired "rimmed" .303 British case in a Wilson case gauge, and the amount the case is sticking above the gauge is how much too far the die will push the shoulder back.
