What kind do you have now? Is it a target model or fixed sight? Five and a half inch barrel or seven and a half inch barrel? How many shots do you get out of it at the range before you have to clean the cylinder and cylinder pin? How does it shot? Does it hit dead on or do you have to compensate, i.e., Kentucky windage? Sorry for all the questions, I'm just damn curious about how they handle all around and what you personally think of yours.
I haven't actually seen the fixed sight guns until very recently. All the old guns were adjustable sighted 7.5" guns and that's what mine is. I think the fixed sight five inch guns are a product of cowboy action shooting which has gotten really popular in the last 15 years or so. I ain't into playing cowboy. If I was, I'd use one of my blackhawks. The Old Army is for USING in the field IMHO, but it'll play games, too. It's ultra accurate. My stainless one was late 70s and had a wider trigger than my blued one. The early ones had a rather narrow trigger and that's why I'm pretty sure the blued gun is an early production piece.
As far as the sights go, it shoots way too high and I have the rear sight lowered all the way down. My stainless one shot high, but not as high as this one. I have to put the front sight blade in the bottom of the rear and hold as if I had a full sight picture, target at the top of the rear sight, if that makes any sense. The cure is to put a taller front sight on it and I'm going to send it very soon to Jule to have that done and the cylinder bored. Then it should be an AWESOME outdoor gun. I intend to carry it hog hunting to back up my Hawkin. I want more fire power than the Hawkin if I just succeed in POing a big one.
This area I wanna hunt is BP only.
I don't know if you can EVER wear out a Ruger Old Army if you take care of it, clean and lube it after every session soon after. The thing is built on a smokeless super blackhawk type frame. It's the proverbial bank vault. Just pull the cylinder, check the bore for pitting. Check cylinder for end play, timing, all the things you'd do with any used revolver. If there is excessive end play, it wouldn't be from pressure of the load, just from being fired everyday for 600 round or something, LOL! I don't think you'll find problems, put it that way, but if you do, bare in mind that the Ruger factory is very good about repairs and rebuilding worn revolvers to like new condition. Main thing I'd worry about with the gun is did the previous owner/owners clean the gun as they should? Is there pitting in the bore from lack of cleaning?
Buying a used Old Army is more like buying a used Blackhawk that's never fired anything, but .38 special than it is buying any other BP replica revolver. The things are QUALITY built and built strong, why the price is up there. It is a modern design gun, too, all coil spring, all the attributes of the strongest factory production revolver made (until the Freedom Arms came along), the Super Blackhawk. This ain't no 19th century design and it uses strong steels and excellent factory fitting. It don't get no better functionally, whether you like the looks of it or not.
And, yeah, I really lament the loss of that stainless gun. I really need to save for another, I guess. It was a heckuva shooter and so easy to clean up. It was a modern gun that you didn't need brass for. The blued one is just as good, I just prefer stainless and especially in black powder for a gun I'm going to actually be using in the field. For range queens, blued is just fine. I'll just have to take my cleaning kit with me on hunting trips, no biggy since the Hawkin ain't stainless, after all. Going to try 777 in that thing, though. Not sure how 777 would work in the Old Army, but might be worth a shot or two over the chronograph when I get the stuff and the bore done by Jule.
