You can make custom speed loaders out of simple PVC pipe and end caps. I like the 1/2 pipe cut about 4-5 inches long. I attach one end permanent and the other cap I paint red, so I know what end to pull off to dump the powder. I carry my projectiles seperate. Although I am going to change a little and try some experiments with the White to see how fast I can load from this manner. Just for fun.
Now my friend does not glue the ends shut. He made a custom short starter and he pulls the white cap which hold the projectile first and puts his thumb over it. He then pulls the red cap, dumps his powder, then sets that over the muzzle. Then with his short starter he actually seats the projectile right out of the other end of the PVC. I do not do that, but it is surprising how fast he can load a rifle. He claims to him, the PVC is nothing more then a breech that has not been seated yet. And of course PVC is cheap.
If the ends are loose at all, wrap a piece of clear packing tape around the PVC and the cap will tighten right up. You can then carry as many shots as you want in your pocket and they are waterproof.
