So I've shot 10 matches of 3 gun and been running in the practical or old tac ops division and have been kicking around the idea of shooting heavy metal since I have a 308 AR and a 1911. I run a JM Pro 930 and like the safety on the mossbergs, it's quick to get on fire and super easy to put on safe when dumping it in a barrel. But most 500's and 590's have open cylinder and no chokes which is less than ideal. I gave some thought to getting a nova if I could find one cheap. Any suggestions?
