I can't get your link to go anywhere except back to this post. Are you linking to the rules on a hosted site like Photobucket or Picasa? Or are you linking to them on a blog or other web site? I would be glad to take a look at them but need a direct link to wherever the rules are stored, and that location has to be accessible to the public. If the rules are stored on your computer and that is what you are trying to link to, then we will not be able to access them.
Never mind, I got to them. I see now that you simply uploaded the file. I'll review them and send some comments later. A couple of things I did notice right away:
1. Your movement rates and firing ranges are very generous considering the ground occupied by a typical unit. Assuming a 48" table width with each side having a 12" setup area, your cavalry will be withing charge reach on turn 2 and your muskets will be within range (conceivably) following deployment. Is that how fast you intended for contact to take place?
2. I realize that these are somewhat "generic" for all Horse & Musket periods, but "prone" really wasn't "done" in the WSS, or even in western European warfare until skirmishers began to come to prominence mid to late 18th century, and then only for skirmishers. Also, Infantry did not yet charge in column, columnar movement was strictly for road march and maneuver at this stage. Early 18th century warfare was still very formalized based on drill books and manuals, and was really still very similar to late renaissance warfare with very static lines and charges at the fast walk for foot and at the trot for cavalry.
