FX Smooth Twist and Slugs (rethinking an FX Purchase)

Jump to latest Follow Reply
Maybe I am missing something about the $800 FX Crown caliber-change kit for the Impact advertised at TopAirGun (TAG). The caliber-change kit seems to sell for $399 (once available) so where do the $402 in extra charges are coming from? 

I came across TopAirGun (TAG) previously in my search for information about the FX Crown. The "company" does not give out a phone number where you can reach them. Instead, they direct you to send them a web-based message/email... which I did but never received a response to my inquiry. So I decided not to even bother to check with them until the posts above this thread linked me back again to TAG and I realized this is the same "company".

My impression is that TAG is seems to be operating a business assuming the FX customers are ignorant and desperate enough to pay for "services" which are unnecessary IMHO for these FX products. These unnecessarily padded FX-product related "labor" charges -such as having you to send him your Crown or Impact to change calibers and to "test" for you- reminds me of the auto dealers/used car sales "dealer preparation fees" or other made-up charges designed to suck money out of the customer. 

A major designed/advertised feature of the FX Crown and FX Impact is that the user himself can replace barrels/calibers within a matter of a few minutes. Are you telling me that the user should pay to ship his rifle to the dealer (and back) and also pay him for doing that very same thing??? I wonder if FX Sweden, or FX USA are aware of these "services offered" by one of their retailers?

Here are his "services":

If you already own your Crown and you order this extra barrel assembly, you will pay the shipping for your Crown to me and then back to you.

Includes:
  • One .25 Removable Barrel
  • Telescoping Shroud
  • One 16 Shot Magazine
  • .25 Pellet Probe
  • Tested only if I have possession of your Impact

Looks like, the customer maybe in luck! Because there is a $526 version of this same caliber-change kit (barrel/liner/shroud/magazine/pellet probe) which DOES NOT include his caliber change/setup and his "test":

.25 FX Impact Removable Barrel
I know what you are thinking... If you order your Crown in one caliber with the "Thorough Testing Option" and think that the "Thorough Testing Option" should include this extra barrel asssembly because it is ordered at the same time... it does not; it is the same as testing two different Crowns- I have to start from scratch to test this barrel assembly and any additional barrel assembly.

Includes:
  • One .25 Removable Barrel
  • Telescoping Shroud
  • One 16 Shot Magazine
  • .25 Pellet Probe
  • No Testing
  • SKU FXCrownBarrel25 
  • Weight 5.1 lb
  • Price $579.95
  • Sale Price $526.95

I called AOA a while back and asked about the change kit. It's $400 for the barrel and $80 for the magazine.

​If you have an existing Impact, that's not bad, but still, when a Streamline is only $1000, sort of makes you wonder if just getting another gun isn't better than readjusting the Impact for another caliber.

​Plus, if you buy the new Impact X, you get the X barrel system as well, so staying in the same caliber, but switching twist rates is only around $110. 

​I just bought the Athlon scope, so that set my gun money back a couple months. Struggling between Impact or Crown, but will not need to decide for a few more months. Definitely want the X barrel though as I plan on using slugs when able and want the most accurate diablo pellet gun out there.

I ended up buying a used Impact with a standard Smooth Twist barrel. For now, I'll just shoot pellets, but when I come up with the $$ for a .22 STX barrel kit and magazine, I'll pick one up. By then, the barrel sets Matt Dubber is helping design might be available. I can shoot for now, and in time the slug barrels should be available. Best of both worlds.

"toku58"The ST"X" barrels can shoot slugs it just doesn't have the ideal twist rate.
Bob_O I don't think the "X" liners have a choke because they are non directional.
The original smooth twist barrels had a sort of choke.

The current X liner for the Wildcat is choked for sure.....I could feel it easily each time I ran the patch worm through it.

Also, one end of the X liner I have is "marked" with a ring (groove) around it. This is the end opposite the choke.

I guess I need to check out my liner if it has any makings?
Never noticed.
Nielsen website use to state that you can't use their slugs with the smooth twist, but you can for the "X" barrel
. Now it states you can with the Slug "X" barrel.
Since the "X" liners have rifling their entire lenght I can't see why it would be choked?
The original smooth twist. was only rifled at the end, so that's why it was choked. 

Someone was saying that the WildCat X was shipped with the smooth tiwist barrel? Not the "X"? But I don't know if that was ever verified?

"Saltlake58"Matt Dubber just did a video about the new X Barrels, and is working with FX to produce an X barrel with the proper twist rates for .25 and .30. These will be available very very soon, designed for the Nielson slugs.
I did pick up an Impact, and am waiting for the slug and other X barrels and liners. This could be fun!

This is exactly what I want for my .22 Impact!
Now that these slug liners are coming out, I think the .22 will see it's full glory! No need for anything with a bigger cross section.

gotta agree. the ability to shoot all ammunition regardless of whether pellets or slugs is important to me. That is one big reason I chose a used Impact. I knew that if new barrels and such come out, I could upgrade and essentially keep moving forward with the same "Lower". I'm the type that once it is setup, I'll leave it alone, so moving barrels is just like getting a new gun and learning all over again. Should be fun when the new stuff comes out.

Huben is a good option and mrodair has one that will work with American sized cast and pellets. Imo the huben is overkill. For that matter fx and daystate are overkill. Beautiful guns and well worth it if you have fu$% you money but heres the truth I bought a gamo urban for 200 bucks and cleaned it and can hit birthday candles at 30 yards just about everytime. I do have to think about my spread and velocities as i dont have a reg yet but I guess what im saying is that there are alot of airguns that can be insanely accurate with half the cost. One out of the box gun that can compete with fx on accuracy and shoot casts is the airfoce condor in 25 cal or texan. The texan 30 cal you can get a 257 barrel for now that rocks bigtime. Anyway I just bought two guns a big bore and a pellet pusher. That way i can plink and send big lead down range Hope this helps.

Harking back to some bench rest testing with powder burners, at the range some years ago, deforming various parts of the projectiles under test; all same Make, model/type, batch, BC, etc. The only deformation which significantly changed point of impact was any that affected the projectile's tail/base.

I believe we all finally agree it has something to do with the aerodynamic effect on the projectile's ability to maintain gyroscopic stability. We were only testing 100m and I forget the barrel twist as it was a while back and not my rifle.

I've found at higher velocities pellets require stronger skirts with no swaging slag, to be more accurate. My theory is that soft/thin pellet skirts deform at higher velocities. The higher air pressures force the softer skirt hard against the inside of barrel and deforms the pellet skirt as it leaves the crown, with nothing to contain the skirt from expanding as it leaves...
