I do that. I have a piece of pipe 4 ft long capped at one end. Filled with kero; drop a new rod blank in, and leave it until needed. I have never had one break on me, and I use only wood rods. I have worn a couple to the point where I retired them because they got a bit thin from rubbing against the muzzles. I give away more than I use myself, but as soon as the tube gets vacated, I put in another stick. I always get my blanks from the local builders' supply; I select dowels with straight, little or no run-out grain. Don't use a rod for loading that has cracked or begun to split.
