I’m pretty sure it was acetone and atomizing that instead of using smokeless. We have used smokeless powder for the lsat 150 years, any interest in changing from powder to a liquid, or a different form of powder?

But you are correct about useable h20

The 416 Warner filled the same holds 223.7

maybe it’s the new math
