[QUOTE="Konrad, post: 1804617, member: 26549"] I have come to the conclusion that the only way to get a good idea of what is going on with a barrel is to scope it when it is new and then, after cleaning all of the copper fouling from the bore each time, scoping again and referring to the original video. Particular attention needs to be paid to the leads on the chamber end and the crown on the business end. Starting with a CLEAN barrel and referring to historical group size is the only way I have found to understand what is happening over time. I have a log book that I track loads and group sizes in. It is easy to adopt a belief about a thing and then be surprised when looking back at the actual data. . Of course, you know that the hotter the flame is, the shorter the barrel life will be. I tend to lean to the best group size regardless of velocity. Sometimes that is a full power charge and sometimes it isn’t. If given a choice, I’ll choose the slower load of two accuracy nodes in an attempt to keep the flame temps and abrasion as low as possible. [/QUOTE]
