Airforce FrankenTalon on the Chrony

[SpindleB]

Apolo Monster 25.4gr, not as tight as group as the Barra. Good consistency speed wise. 2200psi, That 50cc plenum on the Huben Power Cricket Max-ATH really makes a difference. I think I will adjust down to 1800psi see what kind of power i get.

 

[SpindleB]

Reset regulator to 1800psi, kept PW at 4.
Conveniently my order from Pyramyd came in so I had 3 types of JSB Monster.
First up 25.39 Shallow redesign
880FPS

 

[SpindleB]

Next up, JSB Monster 28.55gr
845fps, didn't reset chrony for new weight.

 

[SpindleB]

Finally JSB Beast 33.96gr

794 FPS

I'd say the combination of the 19" barrel, high flow valve and the Max-ATH is a decided winner.

I think I will leave it at 1800psi.
Tons of power and lots of shots, especially with the 1.1L bottle.

I guess the next thing is just how many shots from 4500psi down some value when I get tired of feeding it pellets .

 

[SpindleB]

Filled the 1.1L bottle to 4500psi. Fired a bit over 60 rounds, JSB Take Down 25.4gr. Bottle is at 3500psi.
1000/60=16.67 psi per shot average.
4500-1800=2700
2700/17=158

So a full bottle to reg pressure (1800psi) is around 160 shots with 25.4gr pellets.

Not sure when I'm going to fire 160 rounds...

Looks like that larger reg really working out. I have the smaller 'cricket' reg on a lower powered setup I built up from junk. Now that I think about it, I cant recall the numbers but want to say around 800fps with 8gr .177. I got the reg used, otherwise, I much prefer the look of the one you have (as well as the added plenum volume).

 

[SpindleB]

I've got both the Max-ATH and the Z-valve. The Z has a 20cc plenum vs the Max 50cc.
To get the same results with the Z as the Max it runs about 2200psi vs 1800psi on the Max.

But the 25.4gr pellets, heavy spring, 90g hammer and high flow valve use a LOT of air even at 1800psi.

Have to admit if this gun hadn't been so cheap I'd never have bought an AF gun. Didn't think I was a fan of single shot. It has grown on me.

Now I want to put the 25 cal barrel in, maybe even 24 inch.

I was thinking .25 would be your next go of it. The single shot never bothered me, really. I like the platform, but the only problem...as you've found out... is the same as with any other Mr. Potato Head gun... you end up spending a lot more than what you intended, but at least it's fun!

 

[SpindleB]

And a lot more than the gun will ever be worth.

One late grab from Trajectron is a knurled knob. So much better than the stock foam covered. Solid grip and shorter, not banging my big thumb into the frame.

Took the Sumo off. Put the 6 inch Talon Tunes back on as it is much quieter.

Now the question is, .25 19" or 24" ?
