Thread: 6.5x47 Lapua not chambering

Take a fired piece of brass. Measure the shoulder with something like a hornady headspace gauge.

Size it as you would do normally. Measure the shoulder again to confirm you have bumped it back a couple of thou.

Try to chamber that piece of brass. If the bolt is hard to close, the likely problem is the base. Use a Redding SMALL BASE body die. This is different from the normal body die.
