[QUOTE="royinidaho, post: 97919, member: 2011"] buffalobob, You're pretty much correct except for the determination of which powder will burn cooler. What I am attempting to do is to determine if it is possible to get "any" powder to burn cooler. I am making the assumption that a cooler barrel for a given velocity indicates longer barrel live. What I'm finding out is why laboratories are so expensive. Mother nature doesn't provide a very good one. Keeping the "environment" constant is difficult if not impossible. Today was another attempt that had a couple of gotcha's thrown in my Ma Nature and one flub by yours truly. One thing that is emerging though, is that with a load that has a little less than full of powder behind the bullet, accuracy is definitely improve in the test cartriges. I alway very much dislike when the researcher, at the end of the report states that "more research is needed." Sounds like the project is being milked. [img]/ubbthreads/images/graemlins/crazy.gif[/img] However in this case, that is the case, just in case your wondering why no definite conclusions are being stated. Which is the case. [img]/ubbthreads/images/graemlins/blush.gif[/img] I have a whole new idea for tomorrow. Instead of shooting a shot then measureing, I'll shot all six shots in very rapid succession then measure the temperature rise. Noteworty observation is that with the "check" loads, the temperature rises steadily to the maximum. With the "test" loads it increases in stages which indicates, I think, that temperature is flowing. [/QUOTE]
