My father and I are finally going to take up handgun deer hunting, we will also have shotguns which will be the primary firearm but we both decided to take the handguns out this season. So needless to say I'm all ready to get a deer with my handloads. the only problem is I don't have a clue what powder to use. First off my father will take his new model 6.5in Ruger Blackhawk 357 mag, and I will be taking my new model 4 5/8in Ruger Blackhawk in 45 long colt. I just bought Hornady XTP's in 158grn and 250grn so I'm set there but I'm not sure if the powder I have on hand is adequate for magnum loads. I currently have Hodgdon Clays, Unique, and AA #5. I'm leaning toward H lil' gun but I'm open to suggestions. Also If anyone has loads they would like to share that work good in both calibers with XTP's that would be appreciated as well.
