Hi Doug,
thanks for answer.
I have got all the standard loading data books from different powder manufacturers.

I am just trying to find out whether I can use up a load of VitaVuohri N140 powder which I still have.

N 140 is a slower powder (equivalent approx. H380) than what is normally used in a Hornet load.

I can get 8grs of N140 in the case without compressing it
and wondered what velocity that would give.

Regards from England
