I've handloaded spreaders with the disk and post sold by Polywad. On another site, a poster solved the patchiness issue by holding back an 1/8 oz of a 7/8 oz. load in 16 ga. and loading it on top of the disk with the 6/8 oz. underneath the disk and covering the disk with the remaining 1/8 oz. and securing it in place with an osc then roll crimping.
