I've shot the cowboy trap match at Winter Range a couple of different times. It's pretty much the same as a regular trap match except everybody is dressed in cowboy clothes and using cas shotguns of one sort or another. I used my Savage/Stevens 311 with long barrels. Some actually use their coach guns or shortened '87's and '97's.
One year at Winter Range they had the trap machines throwing all over the place like a normal trap match. Another year they had the machines throwing the clay birds in the same presentation for everybody for every shot in the match. Didn't like that at all. I like the variation. More of a challenge.
