First let it be known what I am about to do in no way is to subtract any credit from TG who did it right. His work was excellent.
What I hope to do is more for myself to have a better understanding of powder burn characteristics by corelating given knowns found in PT trace. The PT program already provides us with what we need to know but I would like to see if this program's capabilities can reveal a little more. Here I want to divide the decline slope into 2-parts. The Burn Out Phase where the sharp pressure drop begins to level out and the Carry Phase with the remaining pressure that carries the bullet to the exit point. While sitting quietly here and enjoying a diet pepsi (maybe one too many, chuckle) I got a feeling to further explore pressure traces and see what they might possibly offer. Now here the PT's program has some additional features (cursors) and I feel they are there for a reason. But to utilize them I would need original trace files in the PT format to get more accurate info. As TG is no longer with us it looks this will be a long ongoing personal project. Below is one of my original trace of 45gr 4759 with a 250gr bullet with the employment of cursors. The red line arrow is a separate addition just to signify the length of the Carry Phase. For now I think I will have another diet pepsi.
