pellet loaders?

[Zzyzx]

I see where Crosman has a pellet loading pen for breakbarrel rifles in .177.

Does anyone know if someone makes something similar in .22 cal? Would like to have one for loading the magazines for my Blizzard.
Also, what works well for making sure the skirts on the pellets are all round and smooth so they fit right? Pushing them into the magazine with the thumbnail makes grooves across them that might(I don't really know) effect accuracy.
