Well different for sure for each gun. Generally around 150bar as thats how they come from the factory.

Crazy Spiraling .177
- Thread starter Bramezy
- Start date
.177 at 150bar?!?!
That's entirely too much, I've only ever set my 600mm .177 impact at 142b to shoot 16gr zan slugs at 970fps and it could go higher.
Try setting your reg between 85b and 105b, you will have little to no waste of air and your spiraling will go away. There's too much turbulence going on

Just to give you an idea, with my last Fx impact m3 500mm with only the rear reg, I was able to shoot 10gr Crosman HP at 990fps with the reg set to 110b, micro at 3.7, Valve at 4 and PW at 16

Your dealing with a different animal, trust me. Airarms, Daystate come from the factory at 150bar and they work great. Its all based on design, its not always about low reg pressures. I have several FX as well and they are about low reg pressures. Avengers are high pressure too.

Hm, never worked on an Airarms, but it wasn't one you mentioned initially. I figured that what you had all your guns set to since you said they didn't work in any of them.

I hear you and appreciate the input. (I did mention Airarms initially as well.
My initial thought would be if it was turbulent air, wouldnt the moderators strip it? and wouldn't it affect it much closer distances too? Im good out to 30y or more but 50+ is no go.
I dont know where the cut off is either, I will find out though.
Its very strange and for some reason it seems to just be me.......I only clean with a patchworm.
Ill dig deeper into the barrels and se if anything is arye that is obvious. If not, it is what it is!

You never know. The Huma mod .30 .177/.22 was causing spirals on my Huben K1 .22, no clippings at all, but the space inside just wasnt enough and caused too much turbulence. Switched it to the FX empty can and it's a different beast, it shoots lights out now.

My .177 airguns come set to 90 BAR, and that is high, with my current 700 mm Epic Two i can turn regulator to the bottom 56 BAR and shoot 10.4 grain pellets at 950 fps, actually way faster, CUZ that is backed off a lot on the hammer.
The Maverick ( also 700 mm barel ) i have shot 13 grain slugs just fine around 70 BAR, but it is more accurate with a 90 - 100 BAR
150 BAR is what i have tried pushing 24 grain slugs.
In the Two i shoot 13 and 16 grain slugs at 80 - 90 BAR for 970 fps

Shoot them faster - then they improve.
I shoot Beast at 1020 fps in my Redwolf and 1000 fps in my Crown-
I tested and hereafter watched slow motion recording of shooting Beast and Monsters from scope cam footage.
It seems like when they go under a certain speed they start spiraling. They are losing speed quite fast, - from 1000 fps leaving the barrel to 648 fps at 100m.
When I watched the slow motions you could observe that the spiraling poi was hitting almost the same spot even with the spirals but at 100m almost 40 cm from aimpoint consistently Without any wind.
I started experience this with Monsters - When i zeroed and shot them at 30 m they where one hole group.
When I shot at 50 meters they were 8" off to side without any wind - Then if i shot 45 meters they were off in the almost other direction.
I increased the speed 50 fps . and problem solved.

Dont think i have tried to shoot the Beasts really fast, but about 970 i have tried for sure, but i will try that.

check your barrel crowns. if you make your own moderators, check your cans internals alignments and lastly, check that the cans muzzle hole is also concentric.

Since it is happening in “all” your guns, you have to go to the common denominator(s).
Pellets.
Or
something you are moving from on gun to the next like a moderator.
Or
If intermittent spiraling - environmental. For example my home range has a large barn at 28 to 37 yards that my pellet flight must transverse. Air around the barn swirls and a A/C is also pushing air when it kicks on. In this later example set out wind flags / streamers every 5 yards and just watch them.
Also, have they ALL spiraled all the time or is this a new phenomenon? If new, what changed?
Or
Oddball possibility - did you get a new air source which has introduced moisture into your systems? Overtime this can cause odd things to happen inside your Airguns you will eventually experience total failure in your guns.
Or
And I experienced this, cleaning debris was left in shrouds and moderators, best to remove shrouds and moderators to clean, so disassemble them and look.
Keep us posted as we all love a mystery.
I have a Redwolf.177 HP that was shooting amazingly well and one day it started spiraling 13.4’s at 40+ yards so poi was low and right———I thought I’d lost my zero but long story short is my battery voltage had dropped and I was experiencing problems that were resulting from this as when I woke up and charged the battery voila.

Sometimes this is not practical especially for field target discipline where we must stay <12 fpe or <20 or fpe.
Hey @Ballisticboy you like mysterious things?

You are right - You will have to have a powerful rifle to shoot them.
But If you are limited by Law or competition rules the 16.2 gr JSB Beast pellets are probably not the way to look for accuracy ...... But if you shoot the beast and you want them to be accurate over longer distances, -they need a good solid kick in the a..
