I cast for my huntsman. I cast the lee 429 240 drain round nose. I do not have to size them. I shoot them in a green hornady sabot and they work werr. I went with the 429 so I would not have to size. I also mold the 429 in a 200 grain flat nose. Both have worked well, but, I prefer the 240. And since I use the 429 they load quite easily which saves the stress on the ramrod. I shoot 100 grains of pyrodex rs loose in my sidekick with the 240 grain and have had great luck. I hope this helps
