OhioGal,A calcuta is basicly a betting auction. A shooter pays a fee to be entered. Then each shooter is "auctioned" before the handicap event. People(not necessarly shooters) bid to "BUY" the shooter in question. The top scores Usually 3 or 4 places pay a portion of the auction pot to the shooters who record the high scores and their"buyers" usually with ties splitting. The "Buyer" gets the biggest share ,with the rest going to the shooter. The split is usually 60/40 or 70/30. At very large shoots the pot can be VERY large, sometimes in the thousands of dollars, although the big buck calcuttas seem to the a thing of the past. They are a lot of fun, but some clubs don't like them and the ATA does not sponsor or condone them. I have on few ocassions seen tempers flare over them, but is a rare occurance. Be advised though, some localities consider them uncontrolled gambling and have laws against them, so always check with the local gambling laws before taking part. Hope that helps a little.
