You planning on using it this year? I believe you will be okay as long as you keep the distance down and take shots within your abilities. Good luck!
I hunt with a 480 Super Redhawk. My first buck last year ran about 50 yds. If not the SRH, I'd be using a 8 3/8" Model 57 41 mag. The gun shoots really good. That gun was purchased to be my deer handgun, but when it came down to it, I bought a larger caliber. I may take the 41 out this year later on.
