Here is a link to the Bluegrass State Games Shooting Page, for those of you who are residents of KY and who might be interested in competing:
http://bluegrassstategames.org/sports-list/sHOOTING/The Muzzle Loader matches will be held at:
Bluegrass Sportsmens League
Muzzle Loader Division (Bryan Station Muzzleloaders)
2500 Handys Bend Road
Wilmore, KY
There will be both flintlock and percussion divisions for rifle and pistol.
The time listed is 8AM-5PM, but you will be able to enter the matches if you show up and register anytime by 2PM. I believe online registration is still open for this event until Thursday the 18th and on-site registration is accepted, plus feel free to ask the contact provided any questions that you have.
