Hi Fergus...how's things from the Land Down Under?
I used 40's exclusively in my Swift, and found the Nosler Ballistic Tips to be quite a bit more accurate than the VMax's. If you have access to some AA2700 powder, that is a good one for the Swift with light bullets as well as WW760. All guns are different, but this has worked well in several Swifts I've seen.
Would you mind telling us how difficult it is to get components in your country? Any weird problems or things you run into?
Take care and thanks for checking in. -Al
