Trail Boss Powder; An old idea
- Thread starter CanAm
- Start date
donut flakes and hollow tubes aren't a new idea. The idea is this: as a regular flake burns, it gets smaller. As it gets smaller, the surface area i reduced, and the burn rate slows. Whereas a hollow flake, when it burns from the inside, the donut hole gets bigger as the outside diameter gets smaller, so that the surface area remains more constant throughout the burn, and ensures a more even burn rate.
Part of what makes Trail Boss so unique - arguably the main thing - is it's very low density. grain for grain, it takes up a lot more volume than other powders. What is the volume density like of this powder that you've found?

Indeed. The science is well known, as it has been for some time. But, I found it interesting to see CIL create a cartridge that many here load for plinking, using a powder that was so simliar to a "new" wonder powder that is well respected.
Not my ammo, but CIL was obviously working on the same requirements of low pressure/velocity, and case capacity, hence the bulky donut powder.
According to the thread http://www.shootersforum.com/409308-post22.html it runs about 1280fps
