They are fun to use, and work pretty well too. I had one and shot a few geese with it using #1 steel in 2 3/4" shells. I set the choke between mod and imp cyl and gave me a pretty good pattern. Open it up to imp cyl and it made a pretty good partridge gun. I don't think you will find a larger mag for it though. Very easy to clean and maintain. To take the bolt apart, simply rotate the 2 halves past its normal closed posistion and it comes apart for cleaning. Have fun.
