First off, 2400 is not a Hodgon product, it is marketed by Alliant.
Since Speer lists Ruger data for your bullet with 2400 powder, no problem there.
HS-7 is discontinued, that is why no current data is found. It is a very appropriate powder for Ruger level loads.
225 HP:
Start - 17.0/2400/standard primer...13.0/HS-6/mag primer
Max - 19.0/2400/standard primer....14.0/HS-6/mag primer
I used to use this bullet in my 4.625" RBH for Kodiak deer in the early 1990s. Over a near-max load of HS-7 (yes, Speer listed data for this bullet/powder combo in their #11 Manual) it killed very well on lung shots out to 50 yards.
