I'd be really careful about giving Miss Scarlet Smokeless Powder too. The ReaperCon version had her with only RAV 4 (I think, since I had the Bill Cody clone as well with RAV 5), but she was pretty deadly for me with her #RA 2 and 15 ammo supply. She may only have a little .22, but she's deadly with it.
Also, from playtesting we have learned that it is a bad thing to give Bill Cody the edge card Smokeless Powder. If he draws it simply make the player draw a different card.
