I don't have a 32 gauge but I do have a 24 gauge.
Cartridges are sporadically available but the only loads that I've seen in the US for the 32 gauge is an anemic 2 1/2" 1/2 ounce load with a roll crimp - essentially a 2 1/2" .410 load. Because of the larger bore I suspect that they will pattern better than a .410.
If you don't reload, you'll probably be unhappy.
I'm happy with my 24 gauge but I'm also set up to reload and roll crimp - all I had to buy was the GAEP roll crimp head for my drill press and components.
