Rules? I've seen Black Powder used quite successfully for larger IM games, and Osprey are planning a colonial set for 2016 that would cover the period. For large-scale skirmishes I use an adaptation of the 'Sharp Practice' TFL rules called 'War Without Mercy' written by Rolf Gein - not yet published (nag Richard at TFL!) but a draft version can be found at the (currently largely inactive) play test Yahoo group of the same name. Maybe it's time to revive that particular project.
