Henry Rifle Forums

BigAl’s post prompted me to shoot my 22/45. I haven’t shot it much since moving to Wisconsin. I shot SV and was having problems with it cycling. Part of the reason is it’s -15F and the other problem is it’s very dirty. I hate cleaning it. Actually I hate putting it back together after cleaning it. In the past this has been one of my most accurate pistols.

I have one also, mine has the shorter 4.5" barrel. I may run a few through it later just for the heck of it also.

Gene, on Ruger Marks, the biggest reason for cycling issues is a dirty chamber and bolt face and you do not have to do a complete takedown to clean that. All you need to do is run a brush down from the muzzle end for a good chamber cleaning. Yes, I know about the advice from cleaning from the breech end when possible, but you're fine cleaning from the muzzle if you are reasonably careful. Then clean the bolt face and extractor and breech area.

As for cleaning the rest of the action, the internal parts can go a very long time without cleaning.

The next issue is ammo choice. If you haven't shot your 22/45 a lot, it may just need more of a break in. I always ran a minimum of 500 rounds of a HV load, such as Mini mags on a new Mark before running SV. If that didn't do the trick with a good SV load, I ran another 500 with the Mini Mags. The good news is that Ruger Marks do very well with HV ammo like Mini mags for accuracy.

Best of luck.

I feel that Rugers are very intelligent firearms and your 22/45 is telling you, “what are we doing out here in this cold”.

Mine is a MK IV but otherwise similar to yours and it likes HV just fine. But in fairness I didn’t run a lot of different ammo types in it but just what I had on hand. Here’s my results.

The Otis cleaning kit will do a great job if you are hesitant to clean from the muzzle.

... I hate cleaning it. Actually I hate putting it back together after cleaning it.

ditto that, especially my semi-autos.

All my .22s have accuracy issues with SV. I now only buy and shoot HV/HP. My favorite CCI Mini Mags.

I shoot only Mini Mag HPs in mine, it is boringly accurate IF I do my part. Putting 50 shots inside a 3 inch bull at 25 yards offhand is unusual but not surprising for me. I do have a red dot. And a Tac-Sol upper. And Volquartson trigger. These are great guns. I am not much of a shooter, so those really help.

Mine is a Mk 1 and I milled the frame so I could add 1911 grips.

I suspect the SV wasn’t powerful enough to cycle the bolt all the way back and it wasn’t locking fully into battery. I bet it might have with HV. Still it needs to be taken apart and cleaned.

Isn’t the Mark IV claim to fame supposed to be that it is easier to break down and reassemble than the earlier Marks?
I went with the S&W Victory it breaks down easy. I still haven’t ruled out picking up a Ruger Mark but lean more toward the earlier models. Maybe it is the challenge of learning to master that breakdown and reassembly.

I got my first Mark in the early 70s and learned how to do the take down by reading the manual. No internet in those days, of course. After learning a few tricks along the way, it never was a big deal for me. I will say, though, that as Ruger QC dipped in the MK III era, some, but not all, MK IIIs were so tight coming from the factory that I had to use a hammer for take down. Those were awful and just made the rep of Ruger Marks being hard to take down even worse. (By the way, the added safety features on the MKIIIs are not arbitrary lawyer proofing on the part of Ruger. Ruger added them to comply with restrictions some states had in order to be able to sell in those states.)

Over the years I did many trigger jobs a la VQ kits for various friend's Rugers. Those can be tricky, but for those of you wanting to try, there are plenty of vids online to help.

As far as Marks being competitive in bullseye shooting, a fully customized Ruger was considered competitive in the lower classes, but I don't recall any of the top shooters using one. In those days, the Smith 41 and the High Standard Trophy were the top guns. Vintage specimens are bring top dollar, now.

Yes, I had a couple S&W Victory autoloaders and they were very accurate, right up there with some Smith 41s I've owned. No match trigger, but very accurate. Great buy for the money. Nothing beats a Ruger Mark for durability, though.
