Re: 300 RUM saami min headspace to datum line?
Hookturnr, Are you using new brass? I had the problem with fired cases sticking in the chamber of my first custom 300RUM. The chamber reamer was minimum SAAMI spec. The brass that I was using had been fired in my factory barrel. Even though it was full length resized and would easily fit into the new chamber, when fired some of it would not extract. My gunsmith had advised me to use new brass with the minimum spec chamber,but since the resized brass fit easily, I chose to ignor his advice. After a month of sticking brass,knocking it out with a cleaning rod , and several case head separations caused by excessively resizing brass so it would fit, I bought new brass, sized it correctly, and the problem went away permanently. Good luck, Gary Campbell
