Thanks everyone for the info. All I picked up from the store was a 25rd belt for the SG, $10. I could not see loading up my pockets with 12ga shells. At some point I do need to replace the SG, when I bought it I had no intention of using it for 3 gun. I'll try out the 18" barrel this week end to see what kind of pattern I get using 4 ~ 6 shot. Thanks again.
