Generally speaking, bullets with wide meplats are the best hunting bullets. SWC's do not have a wide enough meplat for anything more than deer and antelope due to a narrow meplat (nose). If you can find a mold to cast hardcast lfngc bullets, then you can cast your own bullets. Otherwise, Marshall Stanton over at Beartooth Bullets makes an excellent product. I have friends that use his bullets for our Florida Swampdemons. Keep bullet velocities to under 900 fps and your ranges to less than 50 yards and you should have a decent load. I will give you 3 loads from my Lee Modern Reloading Book:
1. 250 gr lead bullet, 11.5 grs blue dot 890 fps (max 11.5 grs blue dot 890 fps) oal 1.550 inches, 12200 cup
2. 250 gr lead bullet, 9.0 grs hs6 828 fps (max 10.5 grs 946 fps) oal 1.600 inches, 13300 cup
3. 250 gr lead bullet, 8.0 grs unique 850 fps (max 8.0 grs 850 fps) oal 1.550 inches, 11800 cup
These loads should work in your gun, but you should think about upgrading to a Ruger Blackhawk in 45 Colt when it is in the budget. Handgun hunting with a very warm 45 Colt load opens up a whole new world. You can then take game up to the size of elk. Hope this helps.
