Green River Sporting Black Powder

Next up, an oldie from Doc White! I have zero experience with this powder as it went out of business before I was born.
I greatly question whether it's true black powder or a substitute.

Many questions about this powder. I noted that the powder is bulky, light and if you look closely, has white throughout the granules, similar to what you'd find in pyrodex.

This 70gr volume load, almost is equal in weight to 80gr pyrodex rs. However, another important note.. pyrodex in the early years was a lot more bulky when they first started out.

Very dull in color, Gray's, whites, chunky, no graphite to be seen.

Sure wish Doc was still alive to answer these questions!

I do plan on testing it out when the weather is cooler.

UPDATED: Looking through some notes, American Pioneer Powder 2fg, weighs exactly 59 grains with the powder measure set at 70gr.

Size of the granual size looks like the cannon powder of goes. Works good in larger bores. Try it but be sensible. Velocity will be approx 20% lower than the same charge for 2f. I've shot alot of cannon powder in cartridge rifles. Food for thought.
