I'm not a chemist, but if you go to Google Books and search for "hydrocellulose", there are several pages of documents/publications which date back to the 1900s and 1800s.... you might find the...

Just throwing an idea out here..... if you had velocity measurements from two different barrel lengths (say, 4 inches, 8 inches), they should indirectly reflect two separate points on the...

I have read that the sulfur in BP becomes colloidal (ie, fluid) at "pucking" pressures and fills in voids between the charcoal and saltpeter particles, cementing them together.

Thanks for the chrono data!
Golden Powder might be comparable to Black Powder in rifles (still waiting for chrono reports), but it sounds like it could be too slow-burning for pistols. Perhaps...

It should be mentioned that nitrocellulose powder has an auto-ignition temperature (ie, "cook off" temperature) in the neighborhood of 300 degrees Fahrenheit (~ 150 degrees Celcius).

I will second that motion. Hopefully somebody will provide some chronograph data.

Your initial batch of five rounds was encouraging. As you experiment further, I imagine you will find improvements to the process (and the performance).

Thanks for the update - very concise data.
EDIT - Instead of IMR-4320/Varget, my GRT simulator suggests that it might be a closer match to IMR-4350.

I hope your velocities are superior to what I achieved. That could be a real boon to some people. If the Albert-Oelberg mixture generated a time/pressure curve capable of cycling a gas-operated...

It is difficult to find online documents which detail how primers were evolving more than 100 years ago. It is not clear to me exactly when FH42 superseded H48. Hatcher’s Notebook mentions that “some...

Can you buy Lead Nitrate where you live? Can you buy Calcium Hypophosphite (or Sodium Hypophosphite)? You would need those chemicals to make EPH20 or EPH25.
