Looking for an independent observation, ok?
Lab conditions were shooting bench in pasture behind the house, as usual.
I'll give you all of the info except one. I don't play fair. [img]/ubbthreads/images/graemlins/grin.gif[/img] But after your scientific nobel prize winning determination I'll unveil the hidden ingredient(s).
I'd like to determine if the test is "pretty much" valid as I was forced by conditions to use two different powders. [img]/ubbthreads/images/graemlins/frown.gif[/img]
But tried to keep velocities similar. Figuring that the same amount of energy is necessary, to a point, to get similiar velocities out of two different powders.
The question: Should it be expected the same rate of barrel heating would occur for two similar powders when producing similar velocities all other variables being the same (or close)?
Here's the results.
