Speed loading black powder with a Lee loader is a cinch and safe too. The biggest time consumer when using a Lee Loader is placing cases in and out of the decapping chamber. I happen to decap at the range, clean my brass and then size. Once sized, I use a priming tool. This is where the speed loading comes in. I now take castrating bands and place them in a reloading block. Just so happens the band is a fit in the block. Now, you can place a primed case in the block and the cavity created by the band prevents any contact with the primer and loading block. Once your block is “charged” with the castrating bands, place all cases in the block and bell, moving quickly from case to case. Insert a bullet and do the same with bullet seating then on to crimping. For me, it’s a faster process than handling one case at a time in a press.
