I will not list a powder charge or bushing. But go to your manuals and select a light 1100-1200 fps 3/4 oz load that uses a relatively fast 28 ga powder. This means Unique or Universal. Believe it or not, there are some Green Dot loads out there - and that's my personal preference.
I agree with Sam. Here's the Green Dot load to start with:
