Well as a fellow engineer, Electrical/Fiber Engineer, from the state of KY, Eastern Ky that is, I am using 130gr loose 777 or 3 777 pellets. I don't have a pressure transducer or peizo setup but pressure is supposed to well below 25K according to many sources. And knight said thats safe. I hope. I won't go above 130gr loose 777 ffg.

I use my chronograph and sierra 5th edition infinity software. I took the BC numbers from the Barnes webside so I assume they are correct.
