I have a very similar load but not exact to yours. I tested it and chrono'd it in a 7.5" Redhawk. It should give you an idea of what to expect form the load. It is:
Bullet: 44-255 SWC (GC) Lee bullet -(.430)
Primer: CCI 350 LPM primer
Test Firearm: Ruger Redhawk 7.5" bbl
Powder: H110 21.8 Gr.
Another similar load
245 Gr SWC (PB) (Lyman 429421 Keith bullet .430)
CCI 350 LPM Primer
Test Firearm: Ruger Redhawk 7.5" bbl.
Powder: 24.0 Gr H-110
Hope this helps.
