Happy Cinco de Mayo!

Today we look at the single stroke pneumatic powerplant. Its history is shorter than that of any other powerplant. Many of you readers were alive when this one came out.

History

As far as I know, Walther pioneered the single stroke. In 1967 they released the LP2 pistol which was the first of several single strokes. That was followed in 1974 by the LGR, a single stroke target rifle. I reported on both of these airguns, and linked to those reports so you can examine them at your leisure.

Was there an LP1? I understand that there was, but that it wasn’t stout enough for release to the public. So the LP2 was the first one to be sold.

Of course perhaps the most popular single stroke today is the Beeman P17. It’s a Chinese copy of the Beeman P3, and I have reported on both of those pistols, also. But better than that, reader 45Bravo (Ian Mckee) also gave us a two-part report on how to reseal those pistols and many of you have done just that.

Description

A single stroke pneumatic is an airgun in which just one pump of air powers the pellet. If you try to pump a second time, the air from your first pump is lost, because the pump head is what seals the air in the gun. Because of that single strokes are of limited power and cannot be made more powerful without a lot of special engineering. And even then they don’t get that powerful.

Because of this, single strokes are often made as target guns. The Daisy 853, 753 and 953 are all single strokes that we have been familiar with in recent years. All are now gone from the market. I wrote a 5-part report on the 853 in which I rebuilt the powerplant of the rifle. That rifle’s accuracy was quite good, though not up to what the Civilian Marksmanship Program now calls a precision target rifle.

The Daisy 953

The 953 was Daisy’s last hurrah with the single stroke system. It was a less expensive sporter type airgun that lacked the Lothar Walther barrel that the 853 and 753 had. And it sold for a fraction of their price. The trigger was lousy, but no worse than a factory 853 trigger, so there was nothing to complain about. The sights were fiberoptic that non-shooters seem to love, but which target shooters despise. But Daisy viewed the 953 as a plinker and not as a target rifle, so in that light the sights were fine.

IZH 46 and 46M

The IZH 46 and 46M (the M stands for magnum — a more powerful version) are target pistols that delighted American shooters for years. Unfortunately the Russian government is being bad right now and sanctions prevent that pistol from being imported into the U.S. airgunners lamented this for years until Air Venturi finally fixed the problem with the AV-46M Match pistol.That one you can buy today and you can also read my report on it.

IZH MP532

What readers of this blog know that very few other Americans do is that IZH also makes (made?) a single stroke target rifle. Ha, ha! The “rifle” was just a pistol in a rifle stock. BB was fortunate enough to acquire two of them that he tested for you in a 9-part report. There probably isn’t much more written in the English language about this Russian target rifle than what’s on this blog.

What many airgunners want

What everyone talks about is building a single stroke with more power. The Brits even went so far as to do so — the Parker-Hale Dragon. Here is an excerpt from a 2008 blog report.

Parker-Hale Dragon — Why don’t “they” make a powerful single-stroke pneumatic air rifle?


“I would buy one in a heartbeat if airgun manufacturers would just get off their collective butt and design what ‘we’ want. We want a single-stroke pneumatic air rifle with enough power for hunting.” That’s exactly what Parker-Hale did. Or rather they accepted the design of an independent airgun designer and put it into production. A single-stroke pneumatic rifle with enough power for hunting.

Well, I lucked into a chance to see and operate a Dragon at the 2008 Little Rock Airgun Expo, and I knew I’d be reporting it to you readers someday. When a reader recently saw one for sale on the American Airguns free classified ads page, he asked about it. I answered his question and asked if he’d like a report, which brings us to today. Since I’ve never tested the rifle the report will have to be thin, but I’ve added a detail photo that you won’t see anywhere but here.

Enter the Dragon


The Dragon is an 11-lb. single-stroke pneumatic air rifle that looks like a PCP with a pump added on. It shoots at just under the British legal limit of 12 foot-pounds, so those .22-caliber Crosman Premiers will probably be going out the muzzle between 575 and 590 f.p.s. Being middleweight pellets, they have to be lower in energy so some super-heavyweight doesn’t push the rifle over the legal limit. The lever is attached to the right side of the action and pivots near the muzzle. It swings through about 105 degrees of arc to compress all the air it takes to generate 12 foot-pounds.

Make no mistake, the rifle has the firing characteristics of a PCP. There is zero recoil and vibration when the shot takes off. Because of the low muzzle energy, the report is relatively low, too — about like a Sheridan Blue Streak with five pumps of air. Thank the longer barrel for that. And thank the weight of 11 lbs. (before adding the scope) for the stability of a field target rifle. The weight seems to come from the extensive – nay, dare I say universal, use of steel components and parts. The Dragon is a lead-sled, compared to a normal PCP. Most of that weight is in the extra pumping mechanism, but the use of steel in the parts is a driver, too.

Make ready!


Ever watch the film Patriot and thank God you didn’t live at the time of the American revolution? Getting a flintlock ready to fire was no simple task. Well, if the rifles had been Parker-Hale Dragons instead of flintlocks, the revolution would probably have lasted a few more years. Compared to a flintlock, making the Dragon ready to fire is a chore.

I forget all of the steps to making the gun ready, but here are the ones I do remember. First, you simultaneously lift up on the safety button and push the trigger forward to set the valve. Then, you pop the pump handle away from the stock, but that requires you to pinch two sheet-steel cams together while simultaneously pulling them away from the stock. Once the lever joint has been properly freed, you swing the lever out and up to the top of its arc, just past the muzzle of the rifle. Next, you close the lever, compressing the air. Then, you cock the rifle, which retracts the bolt, allowing you to load a pellet. Close the bolt and you may be ready to fire. I forget if the safety comes on automatically at this point.

Making the Dragon ready to pump. Before you push the trigger forward to close the firing valve, the safety button in front of the trigger is pushed straight up.Once the safety is up and out of the way, the trigger is pushed forward to close the firing valve. The next step is to pump the gun, but before that, the pump lever link is simultaneously squeezed together and pulled away from the stock to free the joint. Now the pump lever is swung forward past the muzzle and then returned to the resting point alongside the stock. After that, all that remains is to cock and load the gun.

It may sound as if I am criticizing the Dragon’s design as I describe the process to make it ready, but that’s not my intention. I was given a rare opportunity to examine this strange and almost handmade air rifle mechanism, and I vowed to report the process to my readers, if and when I wrote about the rifle. Where else are you going to get this kind of information? I know for a fact it wasn’t reported in the airgun magazines when the gun was new, because I was interested in this rifle for myself.

A single-stroke “secret”

Okay we are back to the present day and to this report. Here is BB Pelletier’s “secret” on getting a little more power from a single stroke. I have written about this many times and I even showed it on the first year (2010) of the television show American Airgunner, which I co-hosted with Paul Capello.

What you do is partially pump the gun several times, without completing the pump stroke. I have done it as many as 20, but after you get going, five partial pumps are good. What that does is flex the pump head, making it more pliable. That allows the pump head to gather more air to compress and that gives you more velocity. On TV we saw a 40 f.p.s. rise in the velocity of an IZH 46. I have shown you many single strokes that respond to this process, so if you have one this is something to try.

Triggers

Single stroke triggers can be very light and crisp, thanks to how little they restrain. Daisy made theirs purposely hard and long because they knew kids would be using them, but they didn’t have to be. They can be light and crisp, too. In fact the trigger is one feature that I think makes the single stroke as well-received as it is. Remember how I praised the trigger on my FWB 600 target rifle?

Summary

The single stroke pneumatic powerplant is its own niche within the world of pneumatics. If you have never considered a single stroke, perhaps now is the time to rethink your strategy.
