Coll, well mate we learn something every day!
I have a mate who's just about to reload for a 9.3x62, so I'll get him to look at Alliant R17 & see what he can do with his.
Mind you he doesn't want hot loads but he may change his mind after this!
Sounds like you've hit the accuracy node on yours as well at the top load - frankly if it works & is accurate then keep that one!
If you feel the need to share your load then please do so.
Something I think we should all do here as a reference to all with the cartridge as the reference in a reloading section!

Might be lucky to get out this year with more work on the family house & my youngest building as well - so you can guess where all my weekends etc will end up!
Best of luck with hunts in future matey, hope we cross paths somewhere down the track!
Kind regards
