Good stuff (mostly!) I love to shoot so am referred to as a cross-dresser with USPSA and CAS interests!
Wild Bunch matches kicked around local clubs for many years --finally officially added by SASS with tremendous responce, and now a standard set of rules. However, some local clubs start at condition 1, cocked and locked and have a variety of categories for various guns.
Your 1897(the current rules only allow 1897 -original or replica and only 1911 45 acp for pistols) should be modified to hold 6 rounds in the mag as many stages require that number--(In CAS, all shotguns are staged empty, action open and usually shoot comstock for knockdowns.) WB is non-comstock --aka virginia count, one shot per target gun loaded with correct # of rounds --chamber empty.
Mernicle-see his web site- has a very popular WB steel lined, holster rig--may as well add 3 double mag pouches as sometimes you may shoot 30 pistol rounds (that',s 5 mags, 5 rounds each plus one in the gun--occasionally a rifle round or shotgun round will get ejected via operator error (or?)so you should have a couple of rounds handy --A belt slide can come in handy.-also made by Bob Mernicle (Bob probably has all in stock but his custom work is usually only about 3 weeks--from experience!)
Some carry a mag (remember the 6th mag pouch?)with a single round should a jam with resulting ejection of a live round happen--much quicker than loading a full mag, ejecting it and bringing the pistol to slide lock--which must happen after every mag.
PF is 150 plus-both rifle and pistol-chrono'd at major matches. Bullets must be lead only. Check out SASSnet.com for more details!
Costuming is circa WWI with military the most popular. Full Race 1897's are available from the Squibber, Johnny Meadows and Coyote Cap-all I know as good folks --should find them via google--
WB is a different challenge --and like the other shooting sports --lots of fun!
Shoot straight!
