Guys lump .357mag and .44mag together as if they were similar. They're not.
The 44mag hits harder past 100yrds than the 357mag at the muzzle. It has more Kinetic Energy at 250yrds than the 357mag at the muzzle...
The Super Redhawk might not have the most attractive lines, but it's quite possibly the most capable factory hunting revolver platform on the market.
The Super Blackhawk sacrifices the integral scope mount scallops, but plenty of options exist to integrate an optic. The Hunter incorporates the scope mounts, AND eliminates the square tip on the trigger guard, whereas the holy grail of the Bisley Hunter includes the scallops as well as a recoil taming bisley style grip frame. The standard Super Black is a fantastic revolver, and with a Weaver 301, it takes a scope easily, and with a set of (butt ugly) hogue grips and a Limbsaver bow insulator, it manages recoil quite well.
Running an optic buys a lot of range, it might be best to start with a red dot, which you might keep permanently. I favor variable zoom scopes to give me extra range, but it's hard to argue with an Ultradot Match Dot on top of a Super Redhawk.
For deer, the XTP's are a fine bullet, the 300grn XTP includes 2 seating cannelures, the lower of which seems to have been made for the Super Blackhawks. Seating in the second cannelure puts the nose right at the end of the SBH cylinder, allowing room for extra powder, and running at lower pressures compared to otherwise max loads - but higher velocities.
