Shooting "single shot" from rifles designed for magazines

hello, I am curious if it is healthy for a rifle to be shot single action by inserting a 22 cartridge straight into the chamber?
Say, CZ 452 american rifle.
By design, for the rifles fed by magazines, as the bolt closes, the bolt pushes a cartridge forward and the rim of the cartridge slides under the extractor and ejector from below as it leaves the magazine and I suppose both do not even move during this process, since the rim slides behind the claw of the extractor.
However, when you insert a cartridge into chamber directly, the extractor and ejector must part away from centre outward and click/slide over the rim of the cartridge that is already in the chamber.

Shooting this way, will I wear out my extractor and ejector faster since there is a lot more motion and friction involved with those two elements or I should not worry about it?

I find it faster and more convenient to shoot from benchrest and load one by one by hand rather than loading the magazines....which are EXPENSIVE and hard to find. I realize there are single shot adapters, but equally tough to find or EXPENSIVE.

This is gun specific, some centerfire rifles for example will not load like this, you have to load them from the magazine, but some guns have an extractor that will jump over the rim and some do not.

Exactly.
Doing this on an M14/M305 for example is a very bad thing. I realize the OP is talking about a .22 and it might not be an issue. But the habit it forms can be catastrophic if applied elsewhere.
If I’m not mistaken, in some cases, as the bolts slides forward and makes contact with the case head, the firing pin can make contact with the primer and cause an out of battery discharge. Search that on here and you will see the results on an M14. I wouldn’t want to be holding it.

Ya, my fear as well, not something that can be a blanket statement. I would be concerned about throwing a bolt forward too hard and causing a gun to fire just by hitting the rim with the extractor.

The 22s I have you can load single shot, but I would not say all could.
 
ok, thanks. I am talking 22 rifle, like Savage Mark II or CZ 452/455. They seem to have similar extractor/ejector and spring set up.
I realize many centrefire are bad idea, I think Mauser actions are by design meant to be loaded from magazine as the big claw extractor can't jump over the rim and may chip. But I am concerned about 22 rimfire only at this point.
 
It is still going to be gun specific, and I do not have either in front of me.

Take a look at how the round gets picked up and put into the chamber, if it is a push feed and the magazine lips just guide the round into the chamber then the extractor is jumping over the rim anyway.

You can also take the bolt out and see how the extractor acts on the round, you should be able to tell pretty easily if it would work and how safe it would be to load single shot, my guess would be that most would be fine.

I had the same thoughts a few years ago. Both my CZ Scout (I believe it originally came with a Single Shot Adapter) and Savage MkIGY (designed and manufactured as a single shot with no provision at all for magazine feeding) have bolts that look exactly like their magazine fed counterparts.

The manufacturers have enough confidence in the durability and reliability of their extractors. I have decided that the manufacturers know what they are doing and have stopped overthinking about wearing out the extractors.

Just go ahead and load your rifle as a single shot and enjoy the moment.

FWIW, I am planning to purchase spare extractors and spring, in case our worries do come true.
 
I have a single-shot adapter for my 2 Anschutz rifles...and just ordered a custom one (out of the US) for my CZ527 centerfire. While I've loaded all of these guns by hand (and my CZ 452) I don't make a habit of it for various reasons, mostly because it's a pain in the *ss. :) However, I've also never considered wear & tear on extractors...OR accidental ignition on a rimfire. Interesting points. Personally, steel extractors (presumably, hardened steel) are one HELL of allot harder than brass, let alone brass that is about .009" thick. I have a hard time imagining how many rounds it would take to start to compromise a steel extractor...or how incredibly fast a bolt would have to close to set-off the primer. I'm no authority on this stuff, but I've personally never heard of...or even read about this happening. Not to say it hasn't.

My opinion~if a company produces a single shot adapter for their rifles...and they're commercially available...why not "bite the bullet" and get one? Clearly, a company like CZ would have asked themselves these questions before producing a single-shot adapter, so buy one..put your mind at ease, and plug away!
 
Buy the SShot adapter. Been using one for years on my Anschütz and CZ452. Not had to replace an extractor yet. Most barrels have a relief for the extractor to ride into. Cut into the barrel steel that allows for single shot adapter use.

Is there a Canadian dealer for the CZ adapter?
 
I have not seen a single shot adapter for CZ up close but I suspect it kinda works like a magazine minus the lips that hold the round inside. The cartridge angle presumably is the same as the magazine, the bolt as it closes, pushes the cartridge toward the chamber and the angle would guide it to the chamber and as it goes into the chamber, the rim of the case slides under the extractors from underneath, so no wear/tear on the extractors. I might have to buy the CZ Camp Rifle which comes with single shot adapter and test this LOL!

Well, it doesn't seem like a significant friction when extractor skips over the rim when the case is loaded into the chamber directly. With Wolverine the CZ warranty spot, it should be easy to get extractors/springs and replace the "worn out" parts.
 
well, just ordered a single shot adapter from Prophet River. Made by Lowey Products. Not too expensive. Any comments on the brand? i think it is a simple gadget so I suppose one can't go wrong with it. Although I got pretty good at sicking those little round noses in the chamber directly using my fingers. That's my singe shot adapter.

Wolverine brought one in for me, no idea if they have any in stock now but they can get it if not.

Guys, don't worry about "extractor wear" by loading single shot... the extractor rides the ramp of barrel steel in the breech face every time you close the bolt no matter how you've loaded the rifle, any issues due to jumping the soft brass case rim are imaginary. As far as slam firing... I would question the overall competence to operate firearms of anyone who would work the bolt so hard for that to even be a remote possibility... if it is even possible to work up that much force/speed over the short distance the bolt can travel anyway.

Thanks..
 
I am assuming you are reffering to a CZ, I cannot speak for. I have made a couple of single shot adapters for my gun and a relatives and it was very easy. I just took a piece of styrofoam and cardboard to make a template and tried it out. After that, I made the piece out of wood I had laying around to the same dimension and as wide as the magwell. I then sanded nice and smooth, used a black marker to color it (I wanted black), then oiled it up as I oil a wood stock. I inserted it and the rest is history. Just an FYI as to mine. I made it so I had to take the lower metal plate and barrel screw out to insert it so it is held in place well without the worry of falling out. This was for an old Marlin Model 80.
 
There is a fellow over on rim fire central that makes an adapter that you load into a standard mag and voila it becomes a single shot adapter. Cheaper than dirt and he just drops it in the mail. really cool and simple ,simple ,simple. I have a couple.

Though all my target .22lr's now are true single shots, I had many magazine fed .22lr's in the past, among them some CZ's . I single shot them most of the times and never had any issues.
