Might be better off to reload....
If you go that road, check out Ballistic Products. Long time ago I had an Ithaca Mag 10 and reloaded steel for it. I got everything from them. My primary loads were #1 steel and #6 steel. The #1 knocked them down and the #6 was great for cripples that have a tendency to dive under water on you.
