Airforce Somebody help me with tunning

[Betohunter]

Hello folks.

I recently purchased an AF Talon in .20 cal , I playing with the power wheel and with the pressure in the tank.
Now I filling aprox 2100 psi stop in 1300 psi with 45 ~50 shots aprox 930 fps with jsb heavys 15.6gr.

I put an oring under the tophat.

But I ear in the past that is possible play with the distance of the tophat .

I don’t an expert lol!! But if somebody have more experience and share me tips I appreciate a lot.

Nobody ?

You should be more specific. What is the problem or goal? It seems like you have it dialed in to shoot a consistent string at a good speed for those pellets…

Wish I could help but don't know anything about airforce. Really like the background where you are at. I might need to get me one of the .20s myself as shooting heavies at thar speed would be great for pesting.

It took awhile to get my .25 condor tuned well.

A previous member TrinityMaker helped me to do it.
Here's some things I remember.

Buy another set of bushings (you can find some inexpensive ones) and put one in so you'll have three on the barrel instead of two, you may have to sand it down to fit into the frame.
If possible buy a maddog stock, makes a Huge difference in accuracy.
Don't use orings, they eventually wear down. Buy some plastic washers to go under the tophat from Tony at Talon Tunes.

I'll have to find the exact tuning he had me do, I don't recall if it's initially done with or without the washer under the tophat. You'll need to remove the bottle from the frame.
The object is in finding the right fps that allows just enough air to push the ammo without having too much coming out of the bottle, this is where the washer comes in, by restricting the amount of air the tophat lets out.
Excess, uneeded air will cause the ammo to slightly tilt at the exact second it exits the barrel due to the groves in the barrel.

I'll look for the video he sent me that shows how to put the washer on. The tophat can be removed and reinstalled without depressuring the bottle.
Be mindful of the high pressure and don't attempt it without either getting someone to tell you how to do it, I find the video, or you already know how to do it.

Your problem is to much pre load on hammer spring. Stock hammer spring is 4". Go to centry spring and order a 3.5" spring # 72337. With a shorter spring the power wheel will function properly. Now you can adjust fps as needed.

Yep looking if is possible more consistent

I’ll check it .

Thanks amigo

You need to play with different starting fill pressures and shoot shotstrings. Example. The string may be 30 shots but you are looking for bell curve. Out of 30 shots you may get a good 20 consistent shots. Then adj starting fill pressure and have fun. Hope this help.

Hey brother,

I saw your listing on classifieds and I have something you might be interested. However, I just made my account and I have to wait 10 days to privately message you. Any way I can contact you? Thanks!

Not a lot of info but I will tale a shot. It seems you have a 18 or 24" bbl and the older model with adjustable th. The orings won't last long as they take a beating. Couple suggestions. Head over to Talon tunes and get adj top hat and a pack of spacers. The tp is the trick for controlling speed. This is all assuming it's the older model. Hope this help.
