I have fired hundreds if not thousands of rounds loaded with 5744. Have yet to experience any of the unburnt kernels in the chamber, and the unburnt kernels left in the barrel are generally pretty crumbly. Even if one was hard enough to roll out the barrel and chamber it certainly wouldn't be enough to make the action of a Sharps malfunction...
Glad you haven’t had any problems. I have.
In original & Shiloh Sharps, Ruger#1 & Rolling Blocks.
Not with every load but with some loads enough kernels can get into the chamber to prevent chambering, also leave hard dimples in the brass after some do chamber.
