Well I already have a HW44 and it is a very nice gun. Still there is nothing wrong with the FX Ranchero either from all I can gather on the net. It does have couple of pluses over the HW one is adjustable power and the other is there is an arrow barrel conversion for the gun.
Still these are both fairly high powered pistols probably made for hunting.
There are other pistols out there made specifically for the type of shooting you plan on doing. They will give you many more shots and likely weigh less as well.
