Single stroke pneumatic rifle? (are there any?)

JB1 easy to cock - as usual there's a 'knack' to it!

[Biker_Bob]

I had a couple of Dragons, they were really easy to cock because of the very clever sliding pivot mechanism. Pinpoint accurate too but extraordinarily heavy!
My JB1 was much more manageable, just as accurate but a bit of a swine to cock if I'm being honest.
Never got my hands on a Sportsman, but that's the one that looks like the best prospect out of the batch of them.
I did worry about the complexity of the Dragon but fortunately never experienced any problems. The JB1 seemed a much simpler animal.

Hi all...i have a passion for SSPs i have an Airlogic....Daystate Sportsman.....FWB....ASI supermatch....I have had a JB1 and a PH dragon....currently have a proto Bowkett (80s) but never had a Laser12 which i handled but never bought....thats just my rifles....dont mention my pistols.....

[norris]

that's brilliant.....
I'm currently looking for: a .22 / .20 Theoben gasram barrel, at least 10" long (not a fenman barrel). Thanks.

What's wrong with a Fenman barrel?

Fx Indy?

Agreed, plus with two levers, you're tending not to 'bend' the tube as applying equal pressure on each lever (in theory )

But it looks that easy to pump, one lever might do the same job?
Great idea hope it goes into production.

Saw the Paradigm at a Shooting Show somewhere and was not overly impressed. It was alkward, unweildly and tricky to cock. It simply didn't look to be a practical design and wouldn't be a commercial success.

That's the thing with single stroke Pneumatics you need to develop the knack of cocking them.

Practicality and commercial success are irrelevant in the air gun world for example buying a PCP then having to buy charging equipment which is either heavy to carry round or requires physical effort to use.OK you can buy small lighter air cylinders/bottles but at the expense of capacity.So not that practical but a great commercial success for retailers?

I like PCP's but prefer springers for the self contain power source!

I'm also a fan of single stock pneumatics and own a Dragon.

If Webley or another company manufactured the Paradigm I would buy one!

The chap presenting the Paradigm, wouldn't allow members gathered to cock it themselves, only he cocked it at the time.
That alone rang "alarm bells" with me !
If the rifle, albeit a prorotype required lets say, "specialist handling" then I could foresee future problems developing on production guns whenever they began to be purchased and used en mass !

Well I've not been lucky enough to see the Paradigm in the flesh, I would like to and talk to its designer.
That too would ring alarm bells but a Dragon isn't straight forward to use.
You have to set the valve in the right sequence, I think mine constantly changes the sequence!

Re Paradigm. I saw it at the Shooting Show when the show was at Newark. I spent a reasonable time with the inventor and had several goes with the rifle. To begin with it was very awkward to operate but then suddenly I 'got the knack' and it was really quite easy. Had it gone into production I would have bought one.
The Dragon is a nice rifle but a bit quirky and I never really understood the principle behind how the power was adjusted apart from the fact that a grub screw was twiddled (Mods: I am not looking for information here!). They are also not too difficult to reseal but clearly need to be used to maintain the seals.
The Daystate Sportsman is easy to work on but two pumps for full power is a bind, and very tiring after a while.
So ... a nice easy single stroke pneumatic that was reliable and easy to work on would, I believe, be a success.
Cheers, Phil

Just wondering what the output would be if a fwb 600 or similar ssp 6ft .177 rifle was converted with a barrel change that had a longer barrel in .22, both being more efficient. Would the output bump up to near the 12ftb limit?

Its a nice idea but dont work in practice.
I found when trying such a mod on a Hw75 that you get an initial increase after 2 inches, then a hold for about 2 inches then a drop off that is very marked beyond that.
In otherwords barrel length only goes on giving us improvement for so long until an optimum is achieved and that comes quite quickly at these kind of power levels.
You actually need a cylinder up like 2ft long and a good 1.25 inches in diameter to get anything increasing in velocity beyond about 10 inches of barrel before tail off arrives.
Going upto to .22 proved very dismally disappointing when webley and daisy did it with the nemesis and 722!
About a .25 ftlb increase ....and terrible tragectory at about the 300 fps....much bigger gains come from the expansion of gas when doing bigger caliber mods in CO2 but air dont do a lot.
If anything its transfer port ratios design size that often improves going to .22 in springers more so than pneumatics.
An 18 inch rifle stocked 46m managed 600 fps apparently ....not too bad but 200 fps light of a humble hw50

The inventor apparently took his creation to China and it can take time to go in production.
It's a pity that it doesn't go in production, preferably made here at a sensible price tag.
