since this is for hunting only i'd go with a stainless steel, single action Super BlackHawk. it can be had for less than $500, with tax on top of that, if you will shop for one. the double action Ruger will cost you at least $70 more, with tax on top of that, i'd guess. and you still would have a (double action) revolver that you'd probably fire in the single-action mode. the SBH can be outfitted with Hogue's MonoGrip and you'll probably see even better accuracy (more consistent hand-to-grip placement and recoil reduction will account for this) than with factory grips. if you get the 5 1/2" barrel you'll have great adjustability of the rear sight (i had to work on it on a 71/2" barrel'd one with a dremel to get it proper!) and a decent sight radius. with good eyesight you can hit an 8 1/2'' by 11'' piece of paper at 100 yards with Ruger's iron sights on their 5 1/2" Super BlackHawk.
i've shot both of them, single and double-action. the single is a simpler, potentially more reliable mechanism, with a great track record for accuracy, power, and reliability.
take care,
