SINGLE NINE OPINIONS?



Log in to see fewer ads
Looking at the Ruger Single Nine 22 WMR. Looks like a solid firearm.

Any opinions?

PD

OK-UPDATE ON SINGLE NINE

Well I got one. The Ruger Single Nine is built very solidly. I will state at the outset that I don't know a lot about handguns generally.

I took the new revolver and a box of CCI Maxi-Mags up the hollow. The first two cylinders were fired from 48 feet. The second set of rounds (32) were fired from 25 feet. My shooting is pretty weak but will improve. I bought this pistol so that I might work on my handgun shooting.

Next time I will use a rest and see what the pistol is capable of. Very solid feel. I plan to get used to every dimension of this handgun.



PD

I can't speak directly to the Single Nine, but I do have a pair of Single Sixes, one straight and one convertible.



Since 1968, Ruger has used a .224" bore with a 1 in 14" right hand twist in all of their .22 caliber .22 LR and .22 WMR single action revolvers, including the straight .22 LR models, to accommodate the .22 WMR used in the convertible model and, more recently, the Single Nine model.

There is a .002" difference. SAMMI specs for the for .22LR are:
land diameter = .217";
groove diameter = .222" (+.0005/-0.0) ; and
bullet diameter = .2255" (+0.0/-.0040).

In comparison, SAMMI specs for the for .22 WMR are:
land diameter = .219";
groove diameter = .224" (+.0005/-0.0) ; and
bullet diameter = .2245" (+0.0/-.0040).

In effect, the .22 LR uses a heel based lead bullet that is nominally .0035" oversized compared to groove diameter and a whopping .0085" oversized compared to land diameter. In contrast, the .22 WMR uses a non heel based jacketed bullet that is only .0005" oversized compared to groove diameter and only .0055" oversized compared to the land diameter.

The .22 WMR has to obturate a lot less in the bore, and would have significant pressure issues in a .222" bore. Consequently, it's partly a production cost issue to use the same .224" bore diameter for the .22 LR only revolvers, but it's also a potential safety issue. If Ruger put .222" bore diameter Single Sixes out in the wild intended for .22LR only and someone installed a .22 WMR cylinder for a convertible model in one, it would create a potentially dangerous situation. The common .224" bore diameter for all of the Single series revolvers prevents that.

----

The end result is that the .22 WMR bore dimensions are .002" over sized for the .22 LR. That doesn't help accuracy with .22 LR. However it doesn't hurt it much either and it's not as big a factor as you'd think. In my experience the Ruger Single Sixes and Single Tens are more accurate with high velocity .22 LR ammo than with standard velocity .22 LR ammo. I suspect the higher pressure helps the bullet obturate better in the oversized .224" bore.

Accuracy wise, my convertible model is capable of one inch groups at 25 yards with good quality .22 WMR ammo. With good quality high velocity .22 LR ammo my Single Sixes are 2" at 25 yard revolvers. With standard velocity match grade ammo, they are basically 3" at 25 yards revolvers. That's not bad accuracy however for a .22 LR revolver and it's far better than most people will ever shoot offhand with one.

-----

Neither of my Single Sixes shooting .22 LR will hang with my Mk I 678 Target, my Mk II 512 Target, my K-22 Outdoorsman, or my S&W Model 17-4. However, my Single Six convertible is right in there accuracy wise when shooting .22 WMR.




In conclusion then, a .22 WMR Single Nine or a convertible Single Six with the .22 WMR cylinder installed is hard to beat for field use. None of my other rimfires can approach them in terms of terminal ballistics or effective range. Consequently, my advice is to either get a Single Nine if you only plan to shoot .22 WMR, or a Single Six Convertible if you want the ability to also shoot less expensive high velocity .22 LR for plinking and practice purposes.

Quite honestly, unless 3 extra rounds in the cylinder REALLY matters to you, the Single Six Convertible model makes more sense than the Single Nine. The Single SIx Convertible is also available in 11 different variations, (4.62", 5.5", 6.5" in blue and stainless, plus a 9.5" blue, a couple 5.5" and 6.5" stainless distributor exclusives, and a fixed sight Vaquero'esque stainless distributor exclusive) compared to just one (6.5" stainless) for the Single Nine.

What are the two blued S/W revolvers? I plan to get a second 22 revolver in the future.

I just got a Single Nine, my first single action and I have to say - I really like it. I have just started getting use to the sights and will have to get on a bench to sight in properly. It's been in the high 90's here and yeah - it's NC but c'mon, it's Oct -time for some cooler temps! I put in my time outside on the farm, I don't plan on shooting till we're cooler!

The one on the top is a K-22 Outdoorsman. It's the 3rd model post war variant and generally referred to as a "Pre-Model 17".

The one on the bottom is a Model 17-4.

The tend to be a little pricey - in the $600-$800 range in excellent condition. However, they are in my opinion better made than the current S&W offerings and compare very well price wise with a new revolver.
