So you wish to have a hunting load do you. Ok here is a good one.
Lee 310Gr RNFP/GC sized at .431 but first check the throats in your cylinder. with 21.O-21.5Gr of W-296 or H-110 Rem Case with a Standard Primer not the Mag primer. And set the bullet out as far as it will go or to say to the bottom crimp groove.
Another if you do not wish to have that much recoil is the 431244 SWC/GC sized at .431 in a Rem Case with 23.0Gr of H-110 or W-296 also with a Non Mag Large Pistol Primer.
As a heads up W-296 and H-110 is now the same stuff.
Have Fun
Here is a 50 yard Target with the 431244 SWC/GC with a Ruger Bisley Super Blackhawk Hunter. Yes it was my bad I pulled one lol.
