Ruger Rimfire Challenge -- Tulsa

[Rastus]

Anybody going to Tulsa for the RRC next week?

My two youngest, a nephew and I signed up.  I suspect I will do quite poorly if I finish at all because I can't take the heat. 

Also, I don't know any of the rules...I guess I should read the rule book....but,...Is there a mag size limit?  Any other quirks?

We are planning on shooting SW M&P 22 pistols and 10/22's.  A Browning Buckmark for backup.....my Mark II is the heavy Gov. Comp. Model so probably too heavy.
