Are we talking 200+lb mullies, or 120lb whitetails here?
Either way a 240 grainer with a charge of 2400, 296, N110, etc. that will give you a muzzle velocity of around 1300-1400 should work well. (Assuming a hollow point design. If its a soft point, you'd only need around 1200 for it to work.)
If the bigger spiecies, you might want to look at a 265/270 or 300 grain HP @ 1100 or better option. Or a good 300grain hardcast lead SWC at around 1000 would work well. Although I'm not sure how well the taurus will handle the heavier slugs.
Sorry I'm not more help, but I'm not sure what weights your particular slug is offered in.
My deer load is a 245KT HCSWC @ 1550. But I use a super redhawk, I doubt your taurus would handle that load, it's pretty stout.
