[QUOTE="Silly_Ghillie, post: 1637846, member: 107271"] What I am trying to say is that the old barrel and old load showed signs of over pressure the [U]entire life of the barrel[/U]. when I worked my load in my old barrel, no matter the powder charge, the primers were flattened and I had ejector kiss marks on the upper end of my powder charges. I worked my old load down until the ejector marks were gone to be safe and ran with it for 1000+ rounds. I was worried about having the same issue with this totally new load, and not being able to see ejector marks if pressure was to be an issue, since that was my only real way of knowing where I was at. my assumption was that the CCI #250's were just really soft. I worked this current load from the bottom up, so the COAL, CBTO, shoulder bump, etc. is not the same at all. In fact, my CBTO is a couple thousandths longer. This barrel came with a "carbon copy" stub gauge, and with the bore being virgin- I have a very good idea on where my shoulder and bullet is going to set and have already set it. I have already ladder tested some loads and worked my way up- and I ran into no excessive pressure signs that I had previously experienced. I'm five grains higher and still not even close to the flattening I was getting with these primers in my old load. I'm not sure where I gave the impression I was just taking the same load to a new barrel, but If I came across confusing I do apologize. [/QUOTE]
