I use Green Dot in my little J frame snub nose with the 148 bullet
since they get along together.

Mine likes a light load of 3.5 grs at 743fps for a light target load.
I can pick the load up to a 188 ME if needed with Green Dot with no problems.

A 158gr LRN or wc might also give you accuracy, if the 148's don't work out.
Green Dot out of my 2" starts at 612fps.
