Going the wrong way?
My Talon in .177 with a 18″ barrel shoots a 7.9 pellet at 1050 fps at all power levels. I need to slow it down for indoor shooting. Am I correct in thinking of shortening the hammer spring? No mods have been done to the Talon.

Finally shot a round of silhouettes with a 3k fill. Shot 65 shots, a few sighters, on just over 1k of air. Those little Ninja gauges are a challenge, even with reading glasses.
Now if I can remember what mildot to use for the range.
Went crazy and tried 800 psi
Comparison between 800 and 1200 psi
I have tested a 13 CI bottle and co2 adapter on my Talon .177, I was trying to get a lower velocity than my regular bottle.
Regulator set to 1200 psi
Crosman Premeir 7.9
848 FPS. SD 5.4
Crosman Premeir 7.9
754 FPS SD 6.7
Regulator set to 800 psi
Crosman 7.9
722 FPS. SD 6.4
Crosman Premeir 10.5
652 FPS. SD 4.9
I decided to go with 800 psi, because I was setting it up for indoor silhouettes.
Should get 60 shots.
Good to hear it worked out.
Finally, got the chronograph fired up. Using power setting 7, which turned out the most stable, shot the following pellets.
Crosman 7.9 gr 820 fps
Crosman 10.5 gr 732 fps
So it fell about where I wanted it, now to finish setting it up.
Slow and steady will win the race. :biggrinn: Glad you got it worked out.
Well, it took almost a year, but I finally broke down and bought a 13 ci tank and installed a 1200 regulator,that I had, on it. The pb shop had the bottle with a 800 psi reg for $59.
So far I found that I can get at least 60 shots before pressure on the tank is at 1500 ps. It is shooting to poi that CO2 did, put a shut off valve between it and the co2 adapter in case it did not work. Now to find a stock, that little bottle if hard on the replaced shoulder. Then I will chrograph the set up.
I get tempted by the Micro tank, but then I look at what I have already invested in co2. However, now that it is 15 degrees outside, I am thinking more about air. The 13 ci tank looks interesting. Archer and PA have one putting out 1100 psi, but I do not know how many shots it will do on my Talon.
If the indoor range is at least 60 degrees the co2 works great. I did find out this summer, that the Talon did not like 95 degrees, one big dump.
This is an expensive option, but how about a micrometer tank/valve setup. That is my plan.
I would like to trade someone who has a micrometer tank exchanged for a full power Condor tank.
So far AirForce sent me a hammer for the Talon. It was shorter in length than the one in the rifle. Still no adjustment, but slightly slower. Experimenting with the CO2 adapter, I installed the ORING. This gave me some adjustability up to a setting of 8, after that it actually slowed down. I found the 6 setting the best.
I had been using Crosman Prem. 10.5 in the tin. Just for grins, I tried some 10.5 from the cardboard box. The speed jumped up by 50 fps. Out of 10 shots, they stayed within 3 fps. Guess I’ll be getting more of them.
I’ll “second” the top hat shim. My Talons power wheel was essentially no function. I adjusted the Top Hat to the width of a quarter and installed an o-ring. My power wheel now allows for adjustment between about 580 fps to 800fps

Stick a washer under the top hat. To slow it down start with .040 should drop it down quite a bit. Then sand it thinner for more velocity until your happy. $5 will get you more than you will ever use. Ive cut my condor down to 400 fps in 22 cal with a .050 washer at 3400 psi.
If you plan on shooting indoors you don’t need a 18″ barrel. Maybe pick up a 12″ barrel and a micro tank. Shoot heavier pellets 10.5gn, lighter hammer. Drop your tank pressure.

Sounds like you are doing great Ray! Been to busy with the new job and all to work on powder burners or airguns!
