$2,000 for a gun that should have never passed QC. I wouldn't waste my time tinkering with it. Just bring it back and change it out for one without the problem and let FX figure out the issue. That's what warranty service is for.

FX Impact Pellet Spiral - Possible Root Cause Found
- Thread starter travels4fun
- Start date
I was able to make it over to AOA with afternoon. They modified the magazine by filing down some of the metal casing around the opening in the casing where the pellet exits the magazine (see pic). I had hoped to have time to see if that fixed the issue but ran out of time. I should have more time tomorrow and will provide an update in the evening.

The hole in the mag. is supposed to be in the middle of the slot. With this one it isn't."travels4fun"I was able to make it over to AOA with afternoon.

If I were you, I would go back and ask for a new mag. Sorry to say, but for such a expensive gun, it is just not done to file down a mag. and send the customer away with it.
And the way they filed it down is not gonna win any beauty contest as well.......

They have no more Impact magazines until the next shipment. I found this out last week after calling AOA about why I was sent smaller magazines with my Impact and long story short they told me they will exchange my smaller ones for the Impact magazine when the new shipment comes in.

If FX truly follows this forum you should have two new magazines in the mail coming to you right now with an apology letter.

Hopefully the magazine "fix" solves the problem. Sounds like Impact stuff is in high demand and therefore, short supply.
Good luck!

I would be surprised if the little damaged skirt is the cause of the wobble.
The head must not be damaged!
Here is a video that shows this.
I think the barrel is the cause, perhaps the pellet scrape on the Shroud exit hole?

I experienced the same problem with one of my guns. Just a little chip or scratch and the groups opened up big time, very noticeable spiraling. On my gun the transfer port hole had a burr and it was scratching the pellets, once I fixed that accuracy went back to normal.

IT WAS THE MAGAZINE!!!
AoA's fix did the trick. I shot both the JSB Heavy MK I and the MK II pellets at powers 5 and Max with no signs if spiraling. I must have gone through 1/2 tin of pellets and other than 2 Flyers' nada problemo. Even the lighter FX 25 gr. pellets on MAX flew perfectly and they were averaging 965 FPS.
I'll post some footage so you can tell me if I missed anything. Should have at least one video up some time tonight.

I knew it! That was my guess. Glad you got it solved. Hope they replace it when they get more.

I had the barrel off and did a dry run of pellets both manually loaded and though the magazine. Only the pellets from the magazine showed skirt damage. I had already pulled the probe out to inspect it and it was fine, Same with the barrel's brass transfer port which was fine.

@30cal Thanks buddy!I It really was a night and day difference. You'll see the footage soon. Now if I can just keep Movie Maker from crashing arghhh!

Kenskylight - I mostly agree with you that head damage is much more likely to cause problems downrange than skirt damage both from the video and Manabe's experiment a while back. (Technically, my way of thinking tells me that any deviation from absolute perfection will have an effect downrange. But, I digress.) Take a look again at the pictures at the beginning of the post. I think I'm seeing a dent on the heads of those scraped up pellets (it's lined up with the scrapes). I can imagine a possible scenario... As the probe pushes the pellet forward and it is (or WAS) getting damaged at the skirt, it canted the pellet sideways and dented (but, didn't scrape) the head adding to the situation. Do you see it too? And, if so, what do you think?
Tom
Guys, while the solution isn't perfect in every way... I think AoA did a decent quick job with the problems they were presented with. They have no Impact mags (currently) to replace that one with, and they have a customer having issues with the product. So, they had to come up with a solution that could work. They did what they could to get the shooter shooting again and enjoying their rifle. Ultimately, isn't that what we all want to do, enjoy our rifles?
I'm sure FX is seeing this, and if adjustments need to be made they'll be looking into it. I could speculate a few things in the manufacturing process that may have caused this to happen but, I have no expertise in that arena and it would only be that... speculation.
Scott, I really hope this has solved the issue for you! If it has, then I guess the next thing you'll have to decide is whether you want to try for a new mag or keep this one that's working. Maybe a little polishing where the filing was done would make it a bit smoother and look a little nicer? I bet opening that hole up a little also makes loading the first pellet a little easier too. Heck, that's a bonus in my book!
Let's see some shooting, ace! LOL!

"As the probe pushes the pellet forward and it is (or WAS) getting damaged at the skirt, it canted the pellet sideways and dented (but, didn’t scrape) the head adding to the situation. "
Here is a photo of my bent pellet probe on my .22 Airwolf MVT that caused the pellet to load canted. Next one shows how much off-center it was before I fixed it.

@fe7565 Ouch that doesn't look good. I love my Wolf MCT and would hate to have that happen. What was the cause and fix if you don't mind my asking?
Upvote 0
I'm curious to hear if Scott has tried any other pellets? I know from experience that not all airguns like all pellets. Just because Ted's Impact likes the JSB 34g MK1 pellets does not mean that everyone's Impact will like that specific pellet too. The JSB 34g MK1 pellets posed a lot of problem because of their length, which is why JSB quickly discontinued the MK1 & started making the MK2 with a shorter skirt.
Tominco may be onto something here. The 34g MK1 pellet head may have been getting a flat spot as it rotated around the magazine. I have noticed that some of my 34g pellets are a VERY tight fit in the magazine.

Yes, they may be right.
But which could still be, the ST barrel is more susceptible than standard barrels for Pellets
with a damaged skirt?!
I can not remember that someone has tested that ever?
„LW barrel accuracy with damaged skirt VS ST barrel with damaged skirt.“
Who has desire to test it?
I have currently no ST Barrel, again only in 1 month.
