Bad Accuracy After Barrel Swap
Hi,
I bought a Talon SS in .177 and I also got a .22 barrel for it.
My question for you is, what is the rubber disk that came with the spare barrel and how is it properly installed with it?
When I was swapping barrels the old black rubber disk fell out with the barrel. Since the change neither barrel is holding accuracy.
My .177 barrel was holding dime sized groups at 45 yards, and now it is hardly holding a 2.5 inch group at 45 yards,
and the same goes with the .22 barrel. I KNOW these are accurate rifles, so could someone please give me some DETAILED
instructions on how to change a barrel properly in case I have done it wrong?
I have watched the instructional DVD that came with the gun a few times and checked the barrel changing section of it
to double check my work, but I seen nothing (or maybe I missed it) on that small rubber disk.
Also, when I do get a decent 1 inch 5 shot group, it will almost always start shooting strays and the groups open back up to
2 or 3 inches regardless of any pellet I use. This has only been happening after the barrel change, with both the .177 and .22 barrel.
The groups tighten up at 10 yards, but the farther away the worse it gets. At 60 yards I got the same results as posted above.
Good 5 shot group, and then strays and 2 or 3 inch groups start happening. The gun is showing me potential, but it’s not sustaining
even though I know the gun can.
Pellets used during my trouble shooting where as follows
.22 Kodiak 21.14 GR
.22 Crow Magnum 18.21 GR
.22 RWS Meisterkugeln 14 GR
.22 JSB Exact Jumbo Heavy 18.13
.22 JSB Diabolo Exact 14.3 GR
.177 RWS Superpoint 8.2 GR
.177 Crosman Destroyers I think around 8 GR
PS: Is the Talon SS Weatherproof? I don’t want to get caught in bad weather during a hunt and walk out of the woods with a knackered gun.
Much appreciated,
-Jeff

Put the other barrel back in to confirm you setup and shooting style.
Follow Wok’s advice.
Something is amiss
Take the best picture you can of the muzzle of your barrel so we can take a look at it.
Also push a pellet through the barrel with a dowel and post picts of the pellet so we can see it from all sides.
With a crazy group like that it often is a problem with the barrel….
Or you have the set screws on the collar holding the barrel loose or the set screws from the frame holding the collars loose.
Something is loose, the barrel is the problem or the scope is the problem. Or the pellet is clipping.
To eliminate clipping remove your cap and shoot to see if it makes a difference
It usually is one of those or a combination of them.
AT 50 Yds your Talon SS should be shooting a quarter of an inch.
Well, This is my last attempt a this .22 barrel. After a full day of messing with the power wheel, various shooting techniques from the bench, and using a hand pump, I have lost hope of this gun ever shooting this .22 barrel inside of 5 inches. I wanted this gun in .22 for hunting, but it’s useless to me. Paper punching in .177 is fun, but I need something i can bust a coon with. .177 just isn’t reliable enough to do it. I want something I can punch paper with yet stretch out to 100 yards if needed to blast a starling, squirrel, or whatever. This is my final group I shot at 50 yards in the last 30 minutes I was outside. I once thought Airforce was a kick ass gun, but it’s been nothing but disappointment. My .22 RWS 350 was more accurate and it even had a BENT barrel.
I’d never touch a wire brush to these barrels.
Cleaned with a patch from the breach.
I think this accuracy issue could be due to inconsistent FPS numbers. I’m getting a chrony soon hopefully and then I’ll take it from there.
I put my .177 barrel back in and boom, 1″ at 40 again with a slight breeze.
W&at did you clean it with, not a wire brush I hope ❓
Did you clean from the breach or the bore ❓
What does the crown look like ❓
Cleaned the barrel and seasoned it with 20 shots. Here is the 10 shot group at 40 yards from a bench with 2,800 PSI fill and the only part of me touching the gun is my hand, lightly on the grip to pull the trigger. I’m also giving each shot plenty of follow through. My 100 yard 8 shot group with the .177 was better than this 10 shot .22 group at 40 yards. I was using the 15.9 GR JSB’s and I had the EXACT same results shooting Kodiak’s. I’m thinking about keeping this gun for .177, selling the .22 barrel, and buying a .22 Marauder. I want to take down critters that requires more punch than a .177, but what good is the additional knock down power if it shoots shit? lol
Yes, these where shot from the bench.
I’m used to shooting springers so it could be my technique. However, I can stack shots at 100 yards with my .17 HMR and the same at 50 yards iron sights with my .22. So I’m not sure on that. I need to get a chrony and see where my velocity is sustaining or if its jumping around.
Can you shoot another airgun at say the 40 yards or better pull in to 25 yards and shoot some groups.
Maybe your technique?
Humm, still not the kind of groups we would expect. Is this from the bench?
Alright everyone,
I adjusted the top hat snug to the bolt and I have gotten very consistent results and a lot more shots per fill. I’m filling to 2800PSI and the gun likes it. I need a chrony so I can really dial the gun in but these targets show I’m doing something right. Also, I got 48 out of 60 in last nights silhouette shoot. No gun issues and someone with a scuba tank lended me a couple fills. When I get the cash I’m getting a carbon fiber tank. Lol
Hand pump is a pain.
Shooting .177 10.34Gr JSB Heavies
First target is 5 shots at 40 yards
Second is a 10 shot group at 105 yards. Top two shots where kinda test shots and the other 8 stuck together nicely. Well, nice for .177 I guess. Haha ;D
I spend 90% of my shooting time going for targets at 100m+, the 2 most important ingredients for an accurate long range rifle is
1. Accuracy-obviously
2. Consistency-just as important as an accurate barrel.
I’ve encountered the same problem you’re having and when I chronied my rifle, I was getting huge shot to shot spreads in among some consistent shots. I see you fill your tank to 3000psi, try 2400psi and shoot at 60m, carry on shooting until the pressure drops off too low. Your groups should tighten up before the pressure drops below the point where it can maintain your target velocity. If it doesn’t then you know its your barrel. I’ve found, shooting 18gr Jsbs, that I get the most consistency just before that drop-off and I get plenty shots as well.
This has worked for me.
Alright,
Just got back from the gun club after the Monday night airgun meet up. We where all shooting 4 sets of silhouettes. The range is only 55 feet (18 yards). I zeroed my TSS in at that distance and poi was fine. After the first round of shooting I had a completely different poi. I had on a filled Co2 bottle. I was also holding this thing like I would a springer to prevent the retarded frame flex with these AF guns. Well, I kept getting poi shifts and it got so bad that another guy let me use his 40 something year old Beeman springer with a cracked scope lens and I hit every target after that with no issue. Out of 60 hits, I only got 36 thanks to the 40+ year old springer. Was embarrassing.
I did see some very fine guns other people had though like the man with the Daystate Airwolf with a digital readout on air pressure. Turns out he’s also a dealer for AOA and Pyramyd Air so I now have a source for cheaper airgun equipment. ;D
I’m not giving up on this Tallon Yet because when this sucker finally gets on target, it’s pellet hole through pellet hole.
Just thought of something.
You said your gun shot fine with the .177 barrel but not good with the .22 barrel?
If I remember right, the valves shipped with a .177 barrel had a stronger return spring to avoid valve dump.
Possibly your valve needs a lighter return spring to work with .22?
Valve work isnt my area, maybe others here can elaborate?
Just set my top hat to .106 on the button. Will let you know how I get on.
Fill 2400
Top hat .106″ no oring
Power wheel 3-12
21g pellets
700fps
Try something is this area

When I received my custom .22 barrel, the groups looked very similar. I was really pissed after waiting 12 weeks for it. At 50 yrds I was lucky to keep all the shots on the target.
The one mistake I made was to clean the barrel thoroughly when I got it.
I put about 300 pellets through it and I could see groups tightening up a lot as the barrel leaded up.
I wasn’t happy with the crown so I re did it and also the lead-in-it wouldn’t take 30gr Piledrivers. Now it shoots a ragged hole at 45yrds and crows within 160yrds aren’t safe.
Something that made a huge difference was putting 50 pellets heavily lubed with bicycle chain lube through the barrel. I wish I could post before and after pics here, the difference is night and day.
Play around with different ideas and definitely try the lubed pellet thing. Check your crown and bushes first. Also push a pellet through the barrel with a cleaning rod and see if it sticks anywhere in the barrel. Pay special attention to the breech and muzzle area. I’ll be watching for responses. Good luck.
