Went to order some .530 round balls today for my rock lock. Nothing doing. Not only are Midway, Buffalo Arms, Mid South, TOW and Graf's are out of stock, but also most of the other sized RB's as well. TOW does have hand-cast RB in .530, but I put the swaged Hornady RB's on back order at Midway and will see how quickly they become available. Why would round balls of all sizes be unavailable? I can't imagine a hoarding run on swaged roundballs. Makes no sense. Wondering if there is an issue with lead?
