3030...I'm a 410 freak! I love the caliber, and own 5 different 410's. You can shoot 2 1/2" shells out of any 410 that has been made. Some won't handle the 3" shells, but yours luckily will handle both.

I wouldn't reccomend the 2 1/2" shells for hunting. They're fine for plinking. They don't do nearly as well a job on squirrels or rabbits as the 3".

Have fun with it!!!
