Talon SS chrony playing.
I’m a lurker on this forum. Have been for a year. Cool forum, and I’ll denial that I ever said that. 🙂
Thought I would make my first post with some boring numbers. 🙄
I tested the straight out of the box Talon SS in 177 with the chrony. I got the talon backing 2005, but haven’t shot it much due to that f**king AF hand pump pumping. 😡 Now I have a air compressor. 😎 😎 😎
My objective was to learn the sweat spot (air pressure) and to see what that thumb wheel really did in fps.
The procedure was to fill the tank to 3k for each string of shots and decrease the pressure by one turn of the thumb wheel. Pellets used for the test were Crosman Primers Heavy (10.5g), just because I have three boxes of them and they are not the best shooting pellet out of the Talon SS.
I started at the high end and descended, so the first setting was 12 on the scale and 8 on the wheel. The number 8 was just picked out of the clear blue on the wheel.
The first string of shot (sos) at 12/8 (scale/thumb wheel) average 839 fps.
sos 11/8 avg 845, with a 6 fps increase.
sos 10/8 avg 841, with a 3 fps decrease.
sos 9/8 avg 847, with a 5 fps increase.
sos 8/8 avg 763, with a 84 fps decrease.
sos7/8 avg 663, with a 100 fps decrease.
sos 6/8 avg 571, with a 91 fps decrease.
sos 5/8 avg 487, with a 84 fps decrease.
sos 4/8 avg 407, with a 79 fps decrease.
sos 3/8 avg 338, with a 69 fps decrease.
sos 2/8 avg 278, with a 59 fps decrease.
sos 1/8 avg 230, with a 48 fps decrease.
It looks like 9 on the scale and 8 on the thumb wheel is the sweat spot for the highest ft lb. When I get a chance, I will fine tune the test to see if I can squeeze and couple more fps out of it by turning the thumb wheel by only a quarter of a turn on each side of the 9/8 setting.

Valve has been acting this way every since I got the tank last year. Thanks to China’s high quality stuff, I have a new gauge on order. Guess I need to look for a new K-valve also. 🙁
Maybe time for a new valve… The needle does jump until it overcomes the AF Tank valve, then it should fill at 100psi per second, or so.
When I close my tank valve the needle drops back by 200psi as the pressure equalizes. So I fill to 2700, shut the valve off, and watch the needle drop back to 2500psi before bleeding and removing my tank.
try it this way.
leave your bleed valve open, crack that tank valve and get it down to a barely audible hiss, close the bleed and watch you gauge climb slow.
You should observe a bounce in the needle when the air starts going into the tank.
Walter….
I’ll gave it a try. Thanks for the tip.

Have fun!
Thanks Steve.
I have seen it. I’ll be fine tuning the top hat this winter.
Try running your pressure down to 2600psi and retesting… I get no drop 15-40 yards shooting Kodiaks – 10.5gn – in my 177SS… I’m betting that’s faster than 850fps.
You are right ssshooter. 16.5 ft lbs.
I have shot 40 shot strings and know where the sweet spot is. I just need to figure out what the psi is.
The valve on my scuba tank makes it hard to get a precise fill. It kind of pops open and shoots up to 2000 or 2500 psi and fills at what rate it feels like.
I have a AA S400 in .22 that I’m also testing, so it taking a while to test everything. But it sure is fun. 🙂

Hi Glenn, here is a link to tophat adjustment instructions from the Quick Reference section under General Chat. You have probably already seen this section, but were perhaps a little overwhelmed by the sheer volume of information:

The gun is pure out of the box stock. With the exception that I removed that crappy safety and added a wokbutt.

Welcome to the fray. Have you experimented/adjusted the tophat?
If I’m not mistaken its pushing just 16fpe of energy and should be pushing 18-20fpe. (**edit from 20-25fpe**)

I don’t own a crony so take my answer with a pinch of salt – however – I did find my gun simply doesn’t shoot well over 2750psi. Maybe it’s time for me to invest 😉
That counts as multi tasking. We don’t do that…. apparently 😆
Well pablouk, it’s really a army flame thrower. 😉 Yea, no kidding. It puts out 3200 psi so I have to refill my scuba tank quite often.
If I could get the gun part of the flame thrower, I could shoot squirrels and BBQ them at the same time. 😛
Is that a “black hole” JR?
Money goes in to never come out. 😕
Thank you for the welcome.
Hmmmmmm, own compressorrrrrr 😎
