I've shot quite a few .410 skeet loads in an old 44XL hammer gun. That's why I mentioned the loads.
I never though OP was asking about rat loads or dove loads w/ larger shot. My misunderstanding.

If I had any red dot (I always considered it a very sooty powder) I'd make up the loads for him myself. I have a garbage barrel full of the old AA .410 hulls.


Out there doing it best I can.
