From what I gather, there's only one ratio that gives a powerful explosion, and all the others give a fizzle. Kirk would have failed to hit that very narrow Goldilocks zone for sure, unless he got extremely lucky. The holodeck theory makes good sense, then.
The other problem is that Kirk would have been hard pressed to create homogeneous gunpowder: there'd possibly be some lumps that work, and then lots of inert lumps. Now that might affect the directionality of the explosion - but in the opposite manner, so that a lumpy powder might provide some random directionality while a properly homogeneous one would provide none.
The main criterion for getting the projectiles to fly as planned would be the ability of the walls to contain the explosion. We see that they did (Kirk is alive, the gems hit the Gorn), which is not inconsistent with the fact that they ceased to be. They simply held long enough, and didn't turn into deadly shrapnel when yielding. (Perhaps they were highly flammable and disappeared through combustion after weathering the pressure just fine?)
