Big Piney has a F class format, i don't think it is an NRA approved match though.
STL Benchrest club shooting an F class, 60 miles west of STL.
Next closest would be OK, I believe......
I have a 1000 yard NRA approved match at Tulsa Red Castle Gun Club next Saturday March 31st. Entry fee is $20.00. Contact me if your interested and I will give you more details.
I just checked out the format they use at Big Piney.... Interesting to say the least. Was thinking about going since it's closer to Fort Leavenworth area, but after reviewing the program, I'm passing on that one......
As a "fun" match maybe..... but not if you're looking for a correctly run match.
