I have been reloading 45-70 and 50-70 for the past few years using 2f black powder. I have only used cardboard wads punched from juice cartons. The wad punches do not have the size on them but they fit snug in the case. I'm looking to buy wads from either buffalo arms or track of the wolf but they list different diameters and thickness. Could anyone tell me the size I should be using? Thanks
