First; welcome to THR!
Well...aside from any possible chemical reactions with your binder that might or might not be an issue, if all you're going for is the ability to load quickly without measuring powder at the range, you might consider using paper cartridges.
You don't say if you're loading for a revolver or for a single shot. With a single shot you can use one of the many "quick shot" type loaders. TC (Thompson Center) and others sell them in various configurations. They carry a pre measured charge, ball and cap in one package, a bit like a modern version of the Civil War era paper cartridge, only much better.
If you have a revolver, the consumable paper cartridges detailed in the sticky on this section, "Black Powder Essentials" are worth a try. If you have a Colt pattern revolver, you could try a paper cartridge with powder only, 'cause the Colts have a bit a hard time taking a full cartridge due to a lack of room. The latter is essentially a single "pellet" measured to your exact desired charge weight, but without having to fuss with binders and their possible effects on powder combustion.
I've had some Pyrodex pellets in one of my possibles bags for years, but aside from being illegal where I hunt (it's loose powder only here) they still have to be carried in tubes. That tube could just as well be a Quick Shot tube with a pre measured charge of loose powder in it, or it could be a comsumable cartridge. Therefore, personally I see no real gain with the pellets.
I really don't want to rain on your parade and I'm sorry for coming off that way. If you want to experiment, I'm all for it. Just be careful, measure your results, and be sure to let us know how it turns out.
