That shotgun ramrod looks fine to me. I do like a little tarnish on the brass, but that will come with use.
It’s always good to have a spare. For shotguns, especially, you can just use a plain old dowel slightly under bore size that you carry in your hand. One of these full-diameter rods is actually easier to use for ramming than the reduced-diameter rod carried in the ramrod pipes. This works very well for multiple shots from one position, but may admittedly be awkward if you are walking a lot and taking snap shots, as in quail hunting.
If you want a really first-class job on a ramrod, get a good hickory rod that is oversized and work the body down to fit the thimbles, but with the driving end tapered up so you don’t need that bell-shaped brass tip. Some people will tell you hickory won’t absorb stain, but I’ve used Laurel Mountain and even Minwax stains on rods, and the results have been good enough for me. However, nitric acid gives hickory a beautiful color when used properly. It is more of a reagent than a stain.
There’s nothing wrong with the rod you have, though. Looks good to me!
