Just a couple of things to consider IF you decide to scope your new shootin iron.
Keep the magnification to the bare bones minimum and go for top end quality. Be sure to check it for parallax while at the store if possible, as this will eat your lunch in the field.
I had a Leupold 4x on my Redhawk for a number of years. Our deer aren't that big and I loaded with 180gr bullets. From the bench it was fairly easy for me to shoot groups at 100yds that were small enough to aggravate the shooters next to me shooting rifles. Having it in the woods, as already mentioned above, and putting the + on a deer was hard enough, keeping it still and where I wanted it was another story all together. A solid rest was mandatory, and not always available.
It is easy to check a scope for parallax, you simply set it on something solid where it will hold still on an object, move your head back until you get the full circle, then slowly move your head from side to side and up and down watching the +. If it moves around while held still and moving your head it will do the same while on target. Unless your holding it exactly the same EVERY time your shots will wander. Some of it can be adjusted out, but sometimes not. Most all have it to some degree but are set at usually 100yds where it is at a minimum. However, if your only shooting at 25-50 this can still be an issue to some degree with some brands. A 1x or 2x is plenty for a handgun IMO, especially if only being used for hunting.
The better the quality the better the glass and less issues you will have. If I were to ever mount something atop of another one of my revolvers it would probably be one of the dot or halo types. This said, there is no substitute for a good set of irons and a lot of practice. Once your dialed in unless you drop it on the concrete or use it for a hammer they will usually stay put. Practice will be you main issue, don't simply set in behind a bench. It is good for setting your sights or checking out a new load, but after that concentrate on field positions, kneeling, prone, using a mono pod, or whatever you feel might come up in the areas you will be hunting.
Once you have a handle on an accurate load and are comfortable shooting it, I highly suggest looking into some of the paper life sized archery deer targets. Set out at 50 and 100yds they give a good example of your acquired skill level when there isn't a big center spot to aim at. Trust me when I say it can be a real eye opener for some. Even if you NEVER plan on shooting to 100yds while hunting it is good practice to shoot to further than you might expect to be. If your grouping well at 50-75yds either off hand or rested then something in the 25-35yd range will be easier to hold still on with the added rush of adrenalin.
I have been hunting with my revolvers since back around 85 when I purchased my first Blackhawk in 41 magnum. It hasn't always been easy, but it has definitely has been a challenge.
Good luck with yours and don't rule out the cast lead WFN's, they do an awesome job on game, and you usually more times than not get two holes every time. Can't say the same about all of the jacketed I have used.
