i have shot the Spartan 20 and I was crushing clays with it....it shouldered very well for me....I have been looking to get the 20 gauge for myself and I love the sporting clays model of the the Spartan but being a poor college student I need all the money I can get...I would say for you to go for it cause I have heard the Mossberg OU to have many problems and I know the spartan has done better
