Don't get me wrong here, I love Dead Man's Hand. It's great for some 1v1 action in the old west. However, I do run a lot of multiplayer games both at home with the group and at conventions (in fact, it is rare that I get to play a 1v1 game of anything). To that end, I recently played a pirates game that was based on using the Fistful of Lead rules from Wiley Games.
The rules worked really well for the game (which had 4 players). To that end, I'm planning to use these rules at the upcoming Conquest Sacramento game convention in early November. While the book does have a QRS, it wasn't detailed enough for me so I created my own.
Sharing is caring, so here you go - my Fistful of Lead QRS. You can download it from here.
Preview pictures of the pages below. This one was easy - just a single page, double-sided (A4).
Note that weapon ranges, etc. are all put on the individual cards for each model in the game. These rules are great for running about 5-7 models per player IMO, but of course could easily work with more models than that if you have fewer players.
