Yes I have a couple of 1300' s too. Mine with the undertaker like the fed. #6 shot. Funny thing is it even patterns better with the 2 3/4" over the 3" . But both deliver awsome patterns. Mine doesn' t like any of the bigger stuff though.

The other 1300 with a Tru Glo strut stopper love fed. #5 shot in 2 oz loads.

I love the gun for running and gunning. Nice and light. doesn' t kick too bad.
