I'd stick with what you've been useing there's not gonna be enough diffrence in the two loads to bother switching. Like the saying goes if it ain't broke don't fix it. Also with a 357 I'd make 100 yards my maximum range for deer. I really would prefer em within 80 yards. If you like the design and fit you could look into a marlin 1894 44 magnum with that one I'd take 130 yard shots. Just my 2 cents
