mto,
Unless there is something major wrong with it you got a real bargin. If you don't reload try RST or Polywads in 2 1/2". Polywad offers a series called Doublewides which have spreader discs. Most German guns are choke pretty tight and the spreaders might be more enjoyable to shoot, i.e. you'll break more birds, clay or otherwise. If you reload you can buy just the spreader inserts.

Enjoy and post some pics when you can.
