 Today I test the velocity of the Mondial Oklahoma air pistol we have started looking at. I was hoping so much that another owner would comment that he had a pistol with a rifled barrel because this one is smoothbore for sure. But no one has come forward yet. And no, the rifling hasn’t worn out of this one. This is a breakbarrel spring-piston air pistol that was made to sell at a low price, but as I noted in Part One, a lot of thought went into its design.

Further tie-ins to the Roger CO2 pistol

Reader Pacoinohio asked for more information about the tie-in between the Oklahoma and the Daisy 100. I have information that comes from two different sources and goes in two different directions. First, while researching Mondial I learned that they also made the Roger CO2 pistol that looks something like the Daisy 100. Many years ago an advanced Daisy collector at an airgun show showed me his Roger pistol in the box that he felt was extremely rare. He also told me that Daisy bought the plans for the Roger and that was what the Daisy 100 was based on. They are not exactly the same and I doubt that many parts interchange, if any, but any designer finds his work easier if he has something to go on. I think that was essentially what happened, if any of it is true.

The other direction I will come from is that I wrote the largest report that has ever been written on the .22 rimfire firearms made by the Wamo corporation. It was published in one of the Airgun Revue magazines. This company is known as Wham-O today and we know them for their Hula Hoops, Superballs and Frisbees. But Wamo also made at least three different .22 rimfire guns, though they claim they never did. The most popular one they made was called the Wamo Powermaster. It was a .22 long rifle single shot that ejected the empty cartridge case and the bolt remained back for loading.

Years ago Dennis Quackenbush, who many of you know as the builder of big bore airguns, told me that he can convert the Daisy 100 into a Powermaster. Yesterday morning Dennis told me that to him it appears that Daisy purchased the Powermaster design and tooling from Wamo and turned it into their model 100 CO2 pistol. That’s why Dennis says it is so easy to turn a 100 into a Powermaster. He says that because he sees little design details in the Daisy 100 that come from the Powermaster and are unnecessary for the air pistol, so it looks to him like Daisy used the Wamo tooling to make their airgun.

Roger
And here is a Roger. I have to say, it doesn’t look much like the Daisy.

Choose one

That’s two different stories of the relationship between the Daisy 100, the Wamo Powermaster and the Roger air pistol. You decide. I’ve told you all that I know.

Performance

So, how does the pistol I am testing perform? According to the Blue Book of Airguns I should expect about 200 f.p.s. I oiled the piston seal and the breech seal days before this test so this one will do as well as it possibly can. Let’s see.

RWS Hobby

First to be tested was the RWS Hobby wadcutter. They fit the breech very tight and wouldn’t even sit flush.

Hobby
That’s as deep as the RWS Hobby would go into the Oklahoma breech with finger pressure.

I knew when I saw how tight Hobbys were that they needed to be seated deep, so the head and skirt would be sized down by the barrel. Just for fun I shot one Hobby seated like you see in the picture. It went out at 175 f.p.s. Ten more when seated deep with a ballpoint pen averaged 244 f.p.s. That’s a gain of 69 f.p.s. from just deep seating. The low for the string was 231. The high was 253, so the difference was 22 f.p.s.

I’m guessing other pellets that are light but not so large as Hobbys will be faster. Let’s see.

Air Arms Falcons

At 7.33-grains the Falcons are heavier than the Hobbys, but they are also smaller, so there is less resistance. I deep-seated them, too.

Falcons averaged 236 f.p.s. over 10 shots. The velocity ranged from a low of 223 to a high of 246, so a 22 f.p.s. spread. Let’s try one more pellet.

RWS R10 Match Pistol

The RWS R10 Match Pistol pellet weighs 7 grains like the Hobby, but it fits the breech almost as well as the Falcon. It’s just a little tighter. Ten of them averaged 254 f.p.s. in this Oklahoma. The low was 251 and the high was 257, so the spread was 6 f.p.s. That’s not only very good, it’s also considerably faster than the Blue Book said, so I assume this pistol is performing well.

Loose breech

I noticed while shooting that the breech on the pistol is loose. However, it is the strangest loose breech I have ever seen. It’s loose when the pistol is cocked but not when it isn’t, which means when the piston is forward it’s somehow affecting the tightness of the breech.

Discharge sound

I tested the sound at discharge with the audiometer app on my smart phone. It’s very quiet when it fires.

discharge Oklahoma

Accuracy?

I don’t have very high hopes for this pistol to be accurate. The inexpensive construction plus the smooth barrel are two reasons why.

I think I will start my accuracy test at 20 feet, rather than 10 meters. And I will look for pellets that fit the breech loosely, or at least not overly tight. I really have no idea of what to expect with this one, but I’m not getting my hopes up.

Summary

The Oklahoma air pistol is an airgun I have long wanted to examine and test. Now I’m getting to. I hope you are finding this as fascinating as I am.

    You know I’m always surprised by the obscure airguns you feature. For the most part I have never seen them before. But growing up in New York City where the the only weapon you could own was a pea shooter. I should not be surprised, but being into airguns for what, the last ten years or so, I still never came across them. Airgun shows are few and far between here, In fact I have never been to a dedicated airgun swap meet or show.
    They were not in stores or advertised in any way growing up. I can’t even recall knowing a single hunter. Only cops and bad guys had a gun.
    Guess I need to look into some airgun books and learn more about these fascinating airguns of the past.
    Does the Blue Book of Airguns offer much info on them or just the statistics?


    • Bob,

      The Blue Book would be an (excellent) introduction for you into old air guns. I highly recommend it. Lot’s of pictures with the stats, histories and other notes. For something like Daisy,… there will be a pistol section and a rifle section. Then, each of those will be broken into Co2, spring, PCP, pumpers, etc.. Usually the oldest guns are shown first. If you get one, you will not regret it. It is big and thick and no internet required.

      Be warned though,…. getting to know/see the old guns could send you down an entirely new rabbit hole. 😉

      Chris

      Only speculation but BB will probably just say,…. “yea,… what Chris said” 😉


      • Chris USA
        Thanks Chris. It will be in my next order. No need for BB to reply unless he wants to promote it.
        I have a lot of books on real steel history but I’ m not sure if they were the reason for my Broomhandles. 😉
        Bob M



        • Bob M.

          Yeah, what Chris said. Do heed his warning though. Here at RidgeRunner’s Home For Wayward Airguns there are quite a few of the old ladies hanging around, waiting their turn on the range.

          Yeah, what BB said. There is a good bit of information in there on many airguns, although some of them are a little skimpy. You will likely find yourself digging around for other sources. Right here is a good source.

          By the by, I have always wanted to play with a Broomhandle for a bit.



  2. BB
    I believe someone mentioned this in part 1 already.

    This should say spring-piston pistol not spring-pistol pistol: Part 2

    “Mondial Oklahoma spring-pistol pistol: Part 2”


  3. B.B.,

    Looking at the Wamo Powermaster and the Daisy 100 it looks very obvious regarding the connection. The Roger pistol can only be tied to the barrel silhouette.

    Siraniko

    PS Section Further tie-ins to the Roger CO2 pistol 2nd paragraph 4th sentence But Wamo also made at least three different .22 rimfire guns, though they calim (claim) they never did.


  4. BB,

    Maybe this was meant to shoot darts?

    Maybe the smooth bore indicates this to be a later version to cut costs of manufacturing?

    Maybe this is one of those rare air mail stamps with the biplane printed on it upside down? This particular barrel maybe missed going through the rifling process?



      • John Walter has a Mondial advertising leaflet in a couple of editions of his book, which lists the basic specs for the Zip and Oklahoma.

        In Italian, the ammunition for this is ‘pallini, diaboli, piumini’.

        In English, ‘pellets, diabolos, feather pellets’.

        In French, ‘balles, diabolos, fleche empennees’.

        I think, then, the last of these is darts. I wonder if, as a toy and blank-firer manufacturer, they started to make airguns and asked themselves “What does this fire – well guns fire bullets, but this can also fire darts as well.” And then, as time goes on and they get more familiar with the airgun market, they’ve realised that the ‘bullets’ airguns fire are, as as often as not, known by the particular name of a diabolo pellet.

        Nota also that the Zip has a ‘gezogener gewehrlauf’ – rifled barrel – which the Oklahoma doesn’t (but can still fire darts).

  5. BB-

    Thank you for delving into the Roger-PowerMaster-Daisy 100 relationship. While the Roger tie-in seems rather vague, the Daisy absolutely is the Spittin’ Image of the Wamo, to coin a phrase (not). I think of Wamo/Wham-o as primarily a toy company. Shouldn’t forget that Daisy was a major player in the toy market for many years. Overlapping circles of interests and people. Not surprising that products and tooling would change hands.

    Errata- Section- Further tie-ins…, second paragraph, fourth sentence- …though they calim (claim) they never…




  6. No takers on having a rifled version.
    You must have one of the very few Oklahoma pistols out in circulation, and a smooth bore to boot!

    I had a friend that followed me into the black powder hobby years ago, he bought a Italian 1860 Army replica, and couldn’t hit a paper plate reliably at 30 ft. He was a good pistol shot.

    While showing him how to properly clean his new revolver, I noticed the barrel was not rifled, while mine of the same model and manufacturer was. Apparently it had missed that step, and had made it through QC to the end user.

    I tried to buy his replica on the spot, or trade him mine and some cash, or even buy him a brand new one, but he declined, and sent it back to Cabelas for a replacement. He said he wanted the manufacturer to know they had issues in their production. (I informed him, they are in Italy, and they make tens of thousands of them, and could care less about 1 return, as long as it didn’t blow up..)

    I wanted it because it would have been an oddity, and it would have made a great snake gun, and trick shot gun for hand thrown aerial targets with birdshot loads. (NOTE: rifled barrels tend to blow the patterns of shot shell loads as the distance increases.)

  7. I have my new Bluebook of Airguns, and love it!
    Just 1 issue, the prices!

    They are accurate for normal times, but unfortunately, these are no longer normal times.

    Due to the time lag between writing, proofing, editing, and printing, 2020 happened.
    The prices are pre-pandemic pricing, and are not indicative of what I am seeing the final sale prices of airgun auctions online.

    It will be one for the collectors.

    Happy Friday everyone!
    Hope you are safe and starting to thaw out from the deep freeze.

    Ian


  8. B.B.,

    Why would Dennis Quackenbush want to convert a Daisy 100 into a Wamo? That’s like a master mechanic wanting to convert a Ford Fiesta into a Chevy Chevette.

    Michael


  9. All,

    It interesting that Georg Luger’s design appers in so many pistols. Ruger, S&W, Daisy 7xx series, and on and on. I’m not well enough informed to be sure that his was the first to use that iconic angled grip design but it has endured.

    Dan


  10. Regarding the loose breech, is it possible that the compression tube has a little play and is able to move back slightly, but when uncocked obviously it will be pressed forward against the barrel face. Looking at the photo of the breech seal in part 1, and a video on Youtube of one of these in bits (but in Russian), it does look like the whole transfer port / breech seal is an integral part of the compression tube, and not formed as part of the frame castings.

    It does also look like the mainspring is retained by a hollow crosspin, which a bolt passes through to secure the two halves of the frame, to allow the entire compression tube / piston and mainspring assembly to be handled as a single unit to ease dismantling and assembly.

    Or does it feel something a bit more mechanical, the barrel lock being affected somehow – although the cocking linkage is in the same position in either case?

  11. B.B. and Readership,

    PA Marketing has gone BIG (BORE) time!
    Let the Big Bore FPE/FPS Wars Begin in earnest: http://enews.pyramydair.com/q/eXR04hrEOaDPESm8fd-W7puUYRqL-L3zweDVn6eX-8CbRvPQxARlMWF8S

    This whole escalation is Silly! More power is really not going to do more than have slugs going/doing through & through(s) with too much energy remaining that is DANGEROUS to things behind the targeted animal! In long range hunting the typically desired energy on target isn’t any higher then 500 to 700FPE among smart hunters. Obviously there are other factors involved the biggest of which is MEPLAT; which provides the best transfer of energy and wound channel diameter.

    Not a smart direction for the manufacturer’s to go!

    End of RANT!

    • Manufacturer’s are merely trying to meet and fulfill existing demand.

      A manufacturer that tries to create demand or fulfill a need in the market that doesn’t exist won’t be around very long.


      • Kevin,

        I certainly agree with your position on manufacturer trying to create demand where there is none. That is a fact as long as consumers are educated about the subject. I don’t believe this is in fact the case just as the super speedy small bore airguns we have talked about are typically not as accurate as a slightly lower velocity version.

        Let them educate their consumers not just throw up escalating numbers. Not a word about precision or potential accuracy is what typically is found in this kind of marketing environment? I understand that high muzzle velocity and Hugh FPE sells in the Big Box stores and online sales.

        shootski


        • Shootski,

          As you’ve noted speed/velocity sells airguns. Horsepower sells cars.

          Manufacturers of airguns can’t educate consumers about achieving accuracy any more than automobile manufacturers can educate their consumers about driving techniques for racing or safety.

          B.B. has been writing and teaching about how consumers can get the most accuracy out of their airguns since the early 90’s and he’s not done.


    • Shootski,

      I do indeed understand. But when you are converting powder burners over to airguns, it take a bit too “slow them down”. They are used to velocities in the 2800 FPS range and FPE through the roof. They just do not understand the physics involved with the lower velocities. Black powder burners and bow hunters do understand the realities involved. It takes a bit for most of the folks to learn.

      Now I am a long range shooter who has been messing with HPA for quite a bit. My objective is to get lead on target a long way off. I cannot rely on expansion, etc. that these people know about with their powder burners. I need to rely on long range precision, etc. if I hope to take my game humanely. Airguns have helped me to be even more so over the years.

      These newbies still have to learn this and until they do the manufactures and dealers are going to try to meet their desires. It comes down to the money. They are in business to make as much as they can by appealing to those who want to spend it.

      There will always be savvy manufacturers who will build for us. If they also build for the newbies, it at least keeps them in business.


      • RidgeRunner,

        “There will always be savvy manufacturers who will build for us. If they also build for the newbies, it at least keeps them in business.” I hope that remains true.

        Other topic: I ordered my SIG ASP20 in .22 caliber with the Synthetic Stock from an Outdoor Outfit near Memphis they sent me an email acknowledgement of the order. Then they billed (PENDING) my CC and sent me confirmation of order execution. I was :^) . Two days later i received an email from them explaining a glitch in their inventory software and that unfortunately their attempt to get it direct shipped from the Supplier (SIG) was met with a not currently available and an estimate of 9-12 weeks. Did I want my order placed on Backorder. I’m waiting. In the meantime i added a question on the SIG Site asking if an estimated date of availability for the ASP20 .22 Synthetic Stock existed.

        shootski



        • Shootski,

          When you say “I’m waiting.”, does this mean you have the ASP20 on backorder? Hmm. I hate to say it, but unless you hunt around and get real lucky, you are not going to find one of these things. It is like me and my Maximus. TCFKAC is not making them right now. The Disco went away. Why? Profit margin. Right now the Fortitude is giving them a better profit margin, so…

          There are other sproingers that are as good as the ASP20. Perhaps you should look at the Weihrauch line. Here is a company that has the experienced shooter in mind. I have an HW30S here for my grandson. If I ever get rid of my Tomahawk I will pick up an HW95. I have shot an HW97 and an HW98. Whoa, dude.

          Then there are the Air Arms line of sproingers, led by the TX200 MKIII.


          • RidgeRunner,

            Good advice for certain.
            I wasn’t really in the market for a sproinger…The Great Enabler got me thinking about the SIG ASP20 all the way back during his review of it. I know he knows about Spring (Gas Ram or Those metal Twisty-Thingies) and he did get all beside hisself about this one!
            Since I have no break barrels other than the Marksman BikeAthlon that I’m only storing for my daughter. I have all manner of .22 and .177 in gas, SS, MS, and PCP so I really don’t need it for filling an empty caliber/power niche. It was for the Break Barrel Technology and the challenge of overcoming the often stated difficulties folks have shooting them. I have taken many pests with my daughter’s Marksman to include at least one pest bird in flight…way lucky shot that! That is NO smooth shooting Twisty-Thingies powerplant!
            So IF this ASP20 chase turns into a rabbit hole…it won’t break my heart. I have too many to shoot and too much to do already ;^)

            shootski


            • Shootski,

              There are quite a few of those metal twisty-thingies that are dead calm to shoot, most especially if it has been properly lubed and tuned. As for the gas rammy-thingies, I know there are bound to be some nice ones out there, but all that I have handled would slap you side the head every time you shot it.

              Sproingers are different. You should pick up a good quality one. One that you would likely be impressed with and would make a good pester is the HW50. Relatively light, mild mannered and once you learned her ways, deadly accurate.


              • RidgeRunner,

                More Enablement! I’ll take it under advisement…since this next airgun (any gun) purchase seems to be a stumbling point with my lovely wife. Perhaps in time I will buy a REAL spring piston break barrel-sidelever-underlever. Since a recent flurry of pistol purchases on her part for me, Custom hand engraved S&W .44 Mag, SIG Supertarget, and AV-46M and grumbling approval of the EMERGENCY (Blog fomented) SIG ASP20 purchase attempt…we will see! LOL!

                shootski


              • Now you have me leaning to HWs instead of the elusive ASP-20. I like that HW puts fixed, non-glowy-thingy sights on; maybe the HW80 in .22 would be a better choice for FM in terms of ensuring sufficient fpe for backyard “pesting” and fun plinking. On the other hand, one of the reviewers on the PA site said he was having no trouble dispatching them nasty iguanas with his HW50. He did not mention the caliber, but the speed quoted makes me think it’s in .177; FM’s preference is still the .22 caliber. Decisions, decisions! My head explodes. At least PA has a few HW50s in stock. Not so for the HW80.

                The suggestion is appreciated. With the ASP-20, FM feels like Charlie Brown when Lucy takes away the football.


                • FM,

                  There are those that swear by the HW50 for squirrel hunting, etc. I think I prefer a little more horsepower. From what I have read and heard, the HW80/R1 can be mighty fussy about pellets, hold, etc. BB can probably tell you a little more about them.

                  As for my personal choice, for a hunting sproinger I might go with the HW95. It drops in there between the HW50 and the HW80 with power, hold sensitivity, pellet choice, etc. You can also usually get an HW95 at a pretty good price.


                  • Hey, thanks for the feedback – had taken a peek at the HW95; definitely will check it out in more detail now; not a horsepower fanatic myself, though a little more power does not hurt as long as things don’t get too much out of control. Also, at the distances I would be shooting, the HW fixed “no-fiber” sights should be more than adequate, even with FM’s less than pristine “headlights.”


                    • FM,

                      Unfortunately, mine aren’t as bright and shiny as they used to be either and most all of the old gals hanging around here have iron sights with no way to mount a scope if you wanted.


  12. I was checking out a dealer over in Europe and noticed there are many models we would really like to have over here but ain’t. I may have to start ordering from there.


    • RR
      Speaking about ordering at the other place

      One the left coast.

      There is a “Like New In The Box” 54 Air King which is the best rating you can get from them and is available.

      I would get it but already got one. 450 bucks.

      And all through time I wish PA would do trades on pre-owned guns.


      • GF1,

        I hear what you are saying, but you would not likely do such unless you just had a lot of money to throw around and do not care what deal you get. I talked with a certain company in the SW USA about trading my .357 HM1000X in on a new air rifle. They were going to give me $900 for it. It was apparently their intent to make a nice profit on the HM1000X AND the new air rifle I wanted. I will keep my HM1000X and not get that new air rifle, thank you very much.

        PA does not do such as they would have to deal with the used inventory, much of which is not going to be as good as the owner claims. They then have to refurbish these used airguns to sell them as their reputation depends on such.

        The company in the SW USA has a different business model also. They are big into internet sales, but also have quite an impressive brick and mortar. They also actively create opportunities for airgun owners to get together, meet, greet and shoot.

        TCFKAC and PA have taken note of the success of such and have begun sponsoring events themselves.

        I have also noted the company in the SW USA is a bit more selective of the low end stuff they carry. I am certain profit margins figure into that. This also insures they are not in direct competition with PA.


        • RR
          Let me know where to sell a air gun for more than half of what its worth. I got a few I’ll sell then.

          Yes I know some of the old ones sell for good money. But what about new ones someone want’s to sell. I’ll pay a little more than half of what its worth new but that’s it.


          • GF1,

            Some will pay more than what it is worth. If you buy an used airgun from those fellows in SW USA, you will.

            A lot of the people will look at the Blue Book as if it is the end of all sources. It really comes down to how much you are willing to give for or willing to sell for. I have seen a badly scratched up and dinged R7 for sale at a airgun show for over $400, because it said Santa Rosa on it. The dude probably still has it. Many years later, I bought an immaculate HW30S for $200.

            If you look around you will be able to sell your airguns to others at reasonable prices. You will never, ever get a decent price at a dealer. Period.


  13. B.B. and USA Readership,

    This is Off Topic but only until you get to the ammunition section. Note that it is NOT limited to firearm ammo:

    https://www.congress.gov/bill/117th-congress/house-bill/127/text?format=txt

    It didn’t take long for this direction to show up. Look at the fees per rifle/gun or worse still the penalties for administrative violations. Not to mention the repeated Psychological Evaluations that the firearm/any ammunition buyer/possessor and family/household will be subjected to!

    This is what Common Sense gun control looks like.

  14. Hello to all,

    I need suggestions/advise….. I was shooting my TX200 MK III (mfg. date 3/24/2014) and the auto safety stopped resetting unless I pulled very hard on the cocking lever. The next day I got 1 shot out of it and then the trigger would not set. When I cock it the bear trap holds the sliding chamber open but the side release will not let me return the underlever. I can de-cock it by pulling the lever down and then pushing the side release but the sear does not set. Any ideas? I figure it’s a broken sear. What would the fix involve?

    Randy



      • BB,
        Thanks for the insight. I did tighten up all the stock screws and the 2 trigger guard screws, but not the trigger adjustment screw. Would that affect the sliding compression chamber travel?
        Randy


        • Randy,

          No. You need to disassemble the rifle and look at the cocking link and the attachment to the sliding chamber. The trigger isn’t right for this.

          HOWEVER — if you lowered the trigger pull too low you may have adjusted it out of its operation range and that could be the problem. You keep takling about the trigger, so is that what’s happened?

          Set the trigger for a heavy pull and see if the rifle will cock again.

          BB


  15. BB,

    Is the new 20 comment limit on the Comment RSS here to stay? I do not like it. IF,… overnight,.. or gone all day,… (and) it has been a busy comment day/period,… it makes it very hard to catch up on comments.

    My 2 cents,………… Chris


  16. B.B.,

    I hope all is well for you and your neighbors in Texas. I also hope that the IT Section of PyramydAir be able to get things straightened out so that we can continue to enjoy your blog and the subsequent conversations that arise. I also do hope that WordPress can be seamlessly integrated into the new format so that scheduling does not become a chore.
