pooch,
I don't know if you are interested in 19th century longrange shooting but the original World Championship match shot on Creed's farm (hence Creedmoor) on Long Island in 1874 was well documented in the New Yorker magazine and many other places. It was a match of national attention. The Americans defeated the English/Irish using cartridge rifles (mostly Remington Rollingblocks) while the Irish shot John Rigby Muzzleloaders. It was a dramatic match, won on the last shot by an injured American. You can read about it in many places including Ned Roberts' "The Caplock Muzzleloading Rifle" among others (or is Muzzleloading Caplock Rifle? I can never remember).

Anyway, today, we still practice this sport with the same cartridge rifles (NRA Black Powder Target Rifle) and USMILT(or something like that) for muzzleloaders. This fall, 10 of us will be traveling to Adelaide Australia to compete for the World Championship which happens every 2 yrs.

The NRA version allows for muzzleloaders, but caters to cartridge rifles. There are a number of matches around the country (I shot a regional 2 weekends ago in Lodi Wisconsin). The nationals will be shot at Raton New Mexico in August this summer.

Here is one place to read about the muzzleloading side of things. http://www.lrml.org/

FWIW, flight time of a Blackpowder bullet out to 1000 yds is between 3 and 3.5 seconds. You get to pull the trigger and roll over into the spotting scope and watch for dust to come out from behind the target. It is truly a blast (pun intended).
