[QUOTE="John Porter, post: 1646249, member: 110240"] eschafer's explanation is very useful to remember. A quick and accurate [in my experience] way to make a cast of your chamber is to full length resize a case and fire a "reduced load" with a 95% full case of ADI Trail Boss Powder [IMR Trail Boss in the U.S.A] and any medium weight projectile. You will notice that the discharge is quite "low energy", but it is enough to fully fire form the brass to your chamber without distortion. I once did this with three different makes of brass in a competition 308 chamber and all three came out with not even a thou between them. [/QUOTE]
