I have an '03 that I acquired some time ago with an odd problem. It has a good looking, shiny SA 42 barrel, perfect headspace - and every time I fire it I must open the bolt with great effort. This is with CMP Greek Ball ammo. There are brass smears on the bolt face from the effort of opening it.
If headspace is OK, what else could be wrong? How much should the fired cases normally expand in the chamber? I'm getting .005-.007 on the case, and up to .010 on the neck, measuring off a stock HXP round.
Is reaming the headspace all that it takes to install a new Springfield barrel, or does the leade need to be cut, too? Thanks. CCInformation
