S&W 686. I can't seem to understand the rule. Is max 6 rounds at start, then one can run 7?

Minor PF can load up to 8. Major can only load up to 6.

No, maximum of 6 rounds fired before reload if Major PF  declared, 8 if minor PF declared.

This is the rule,  the way I read it,  after the first 6, then you can, in this case, go 7.

Poorly worded, should simply state , max of 6.

It means that if you have declared Revolver Major and pull the trigger on the seventh round whether it is the first moonclip of the stage or the last you will be be bumped to Open division.  Any violation of declared Division/PF bumps you to Open.  The only exception is if you declare Major and only chrono Minor everything is scored Minor with no bump to Open.  If a Limited-10 shooter is caught with 11+ rounds in a magazine after the start buzzer he is bumped to Open not Limited (same for a Production shooter). Likewise a Single Stack Major declaration caught with 9 rounds in a magazine after the buzzer would also go to Open.  So the same applies for Revolver you can use a 7 or 8 shot Revolver in Revolver Major but if you fire that seventh round before reloading you get to go to Open.  Have fun.
 

Unfortunately a 686+ would really be an awful choice for USPSA Revolver division.  With the rules as they are that 7th round does not gain you too much given that so many targets are double taps and USPSA still has the rule of no more than 8 shots required from one shooting position.  You could shoot Major but that extra round is then only a trap to bump you to Open.  And in Minor the lack of an 8th round means you will be reloading as often as Major Revolver on nearly every stage while getting scored Minor.

Didn't specifically obtain for matches, but figured it would be suitable, that is until I read the rule. I agree there are better wheel guns for this division but kinda bummed that its not. I still think the rule needs to be worded to make it clear, max of 6 for major, max of 8 for minor.

Thanks.

Edit: Forgot about the rule of 8 per position, I am used to Single Stack and Production so with mandatory reloads on most stages its slipped my mind. Thanks again for your help.

No problem. Back when they first made the rule change there where a few good discussions about the ramifications over at Brian Enos' forum.  Many agreed it could have been written a bit clearer.

 

That's what you get for shooting a wheelgun

Indeed, the Redheaded Stepchild. Still what better way to have fun with your pants on. Haha
