We do simultaneous monthly WB/Cowboy shoots with no problems with either regimen. We all use the same steel, same courses of fire [first 10 pistol] with the only difference being WB will have 5-10/stage more rds to fire. We will have one or two stages where we advance downrange to the rifle targets to engage with those extra pistol rds. WB also load their sg’s at the loading table. As a WASA club we allow self loaders at our monthly shoots, I’ve shot my 9mm Astra, a bud shot his Luger, another a C96, shot one match with my Webley Fosbery and a MkVI . It’s supposed to be for fun. Next month I’ll don my RE tunic, pith helmet and shoot 2 Webleys and a 1866 musket with fixed bayonets on the anniversary of Rorkes Drift.
