Deluxe Stock

Quick update:

Here is the prototype deluxe stock on a Caiman with a CF shroud.




We're considering offering a deluxe stock as an upgrade option. Here's a prototype we're playing around with, thanks to Keith W who consulted with the design.

Air Rifle Origami Pt 2

I have been wonderin' how this project was coming along. It's been a particularly busy week for me, I haven't been checkin my spam infested inbox, then Noli surprises me with this:








This configuration will only be available on the Caiman for now. The stock swings open from the folded position and is locked into place by the thumb screw on top of the swing. It is also adjustable for LOP by a set screw. It was designed it so that it can be fired even with the stock in the folded position. Preeetty cool.

Air Rifle Origami

We are close to perfecting the long awaited folding stock, although we are still trying to make it work with the Tornado. So for now, only the Caiman will be available in this configuration.

To make it really compact, the rear stock folds flush against the side of the forearm. It will also have two set screws accessible from the bottom that will let you adjust it for LOP. The folding mechanism is massive to give it rigidity. I am really looking forward to what promises to be a fun little quick take-down carbine.







Stay tuned ....

25 cal Bigboy Caiman


We have been experimenting on a .25 caliber Big Boy Caiman with a 20
inch HW barrel for the export market. Noli just reported what he's getting so far:



Pellets: Beeman FTS (19.5g approx)

1st Shot: 904.9fps


20th Shot: 908.8fps


30th Shot: 908.22fps


40th Shot: 900.1fps


50th Shot: 896.0fps


60th Shot: 909.1fps


70th Shot: 890.0fps


Shot to shot dev: 4 - 6 fps

Starting fill: 3,100 psi
End Fill: 2,000 psi


Now, to also make a related theory, we expect the new 19 grain .22 cal Hystans to perform similarly, but with more shots of course because of the added pressure created by the smaller volume of the .22 cal barrel.


Updated, pics up.

Doin The Math....(Big Boy performance numbers)

I hate numbers, but Harry Fuller from OZ was kind enough to do give us the Big Boy Caiman's performance numbers in his post at the Yellow Forum:

According to the data:
220 shots between 923 and 944 fps .. say Mean MV 933.5 fps.
3100 to 1700 psi air usage; say 213.8 to 117.2 approx bar.
96.6 bar pressure drop.
11.6 grain pellet for 22.45 fpe.
Tank capacity 430 cc.

22.45 fpe x 220 shots = 4939 total fpe.
96.6 bar drop x 430 cc = 41538 bar-cc / 4939 = 8.4 bar-cc/ fpe.

AND only 21 fps Extreme Spread for 220 shots at 22.45 fpe with a .177 cal ............

I wonder how good the figures would have been if Noli had only shot say 100 shots and then stopped?....... Wonderful stuff happening just north of Australia. I am old enough to remember when Philippine soldiers were training just 12 miles across the mountains from where this little boy was just getting his first shooting lessons from his dad with a Daisy. I remember those soldiers foot slogging across the rain forest clad mountains and past our house, with not 50 yards and a creek separating us, as they made their way south on some exercise. Those were dark days in our lands.

Good on'ya Chris and Noli...... I am saving my pennies ..... Kind regards, Harry.

Mr. Noli and the Multishot....

Seeing as this lil sweetheart of a gun is just about sold, we took the opportunity to run a few pellets through it to make sure it is shooting well. Here's a quick vid...



That's 11 shots people (Noli didn't load it completely hehe), and it cycled nice and smooth. Absolutely fantastic.
