Please tell us more about this shoot! I have just moved to South Dakota and have family in MT and may be interested in going with a little more info. THANKS MUCH,
Charlie Fleger at Hill Rod&Gun can give you the details
http://www.hillrodandgun.com/feedbackcoming.phpThere will be SXS and pump gun events. Guns must be from the 1950's and earlier. There are several sub catagories inside each event such as hammergun, light game gun and subgauge. It was a very good time.
Last year I shot my 1906 J. Blanch & Son 16ga sidelock. I will again use it along with my 1912 Charles Daly 185 16ga. Good guys showed up with some nice old guns.
