Well you have different load data than i have.
my Hor. 7th list W296 at 36.7 is a max load with the FA revolver and loads and the recomendations for loads for othe firearms chambered in 454Casull perhaps should be loaded up more cautiously.
And i load my FA using the load tables printed from the FA web site and your load is listed starting at 26 gr of W296 and max at 38gr same powder.
So i think dahermitt has answered truthfully.
When you do the video do one on a remote trigger pull and the revolver free to exit stage rear. but with only one load in the wheel.
i am currious as to how far it will travel in the other direction?
