I think this is a great idea I hope it takes off.I would love to see this at the local level.thanks for promoting a match like this.

We just finished a Black powder bench rest match at the Old Saratoga Muzzleloading Club.  Its been going on for a few years but only a couple of us have been shooting in it.  We're limited to single shot cartridge rifles using the same basic rules as BPCR with the exception of any scope or power.  It is shot at 100 yards using the NMLRA 50 yard round ball bench rest target.  The "X" ring is roughly .375" with the 10 ring .900" half the bullet or more to count.  We've been using mostly .32-40's and getting a 50 is really tough.  So far it's only been done once.  Shooting a .32-40 using black powder is a frustrating experience!  There are at least 5 other events from 100 to 200 yards, bench, offhand and sitting.
30 years ago, you had to arrive early to get a spot to shoot as there were a good many competitors.  Today it has dropped off so much many of the events don't get enough competitors to fill out all the awards.  There were several other clubs that had similar events but have all disappeared.  I like the idea of the event but don't travel long distance to shoot any longer.  Check it out, OSMLC next to the Saratoga National cemetery.
