Stick gun powder is typically nitrocellulose only, or only a few percentage nitroglycerin. Ballpowder is always double base both nitrocellulose and nitroglycerin and uses up to 40% nitroglycerin.
Stick powder burns much cleaner but is lower density.
Ballpowder is dirtier but higher densityand appears to usually be cheaper than stick powder.
Also stick powder is much less temperature sensitive than ballpowder.
With some loads it gets to the point where you can't fit enough stick powder in the case to make it function properly.
I use AR15 with a silencer the silencer blow back with the ball power make the gun so dirty. 20 shots of ballpowder with a silencer is as bad as shooting hundreds of rounds with out the silencer.
I have cycling problems from adding a silencer, rifle length guns don't seem to mind, but shorter carbines cycle hard and fast when you add a silencer.

The constantly malfunctioning dot gov guns seem to have worn out magazines or are just worn out. If the gun is constantly short cycling, it's probably got worn out bolt carrier group parts. If it's trying to double or triple feed rounds, the mag is likely worn out or damaged.
If cases are getting stuck in the chamber the extractor is worn, rounds are over heating in the hot chamber before firing and over are pressuring, or there is most likely dirt on the ammo.
