I got some Hodgdon Superformance powder at the weekend with the intention of using it with 55 grain sierra soft points in a 22 - 250.
There is a limited amount of data on the tub and on the internet. However, the lightest bullets the data covers are 60 grains for the 22 - 250.
I wonder if anyone has a copy of the latest Hornaday manual (I think its Vol. 9) or the latest Hodgdon manual (I think its Vol. 12.) If either of these have the data I need I'll order a copy. However, I don't want to get one and then find it doesn't have what I need.
Thanks for your help.
