Barrel Fussy and Spiraling, what is the reason??
Guys,
however we have discussed these issues long time ago,,,but i would like to discuss it again and there might be more good idea with some new members or other old members that have got more experience now,,,
i just wondering to know why some of the barrels will be pellet fussy or shooting spiral?? is it from the factory reason ?? or it is because of the user??
pellet fussy and spiraling will happen only with choked barrels or none choked barrels??
what is the main reason that create the spiraling and make the barrel become pellet fussy,,,???? what is the solution?? how can we treat with the guns to avoid us from these
my Edgun long .22cal was spiraling at 900 FPS ,,,while my .22 cal STD shooting very accurate and straight even at 970 FPS without spiraling….
now, i got Short .22cal and STD .25cal ,,but still not checking for the spiraling…
i wounder to know only these happening with small calibers or happen with .30cal or bigger???

Since I am located in Sweden I can get FX pellets almost the same price as jsb, the fx pellets also have different skirt size and higher quality (less damaged in the tin) one reason apart from quality control could be that the die used by say Edgun is a newer less used (and therefore less worn)
Mike, the following pellets are made by JSB (correct me if I’m wrong)
JSB
Air Arms
FX
Daystate
Edgun
The difference is the die or machine they use for the pellets, for example Air Arms Pellets have their own machines and higher quality control than normal JSB, I would assume the same for Edgun pellets, therefore better quality than normal jsb.
But they are the same lead, an email was sent to jsb and the Confirmed that the same lead went into all pellets
Spinj….
That is a very good and informative reply. .. thanks for your explanation. … we must consider all points you all mentioned. .. i believe we got new infos about the spiraling ….
Mike…. for sure that Edgun pellets are made by JSB company, even rest of the pellets like AA , daystate and all that got the same shape of the JSB pellets….
But i have to admit that clearly Edgun pellets are better manufactured that my JSBs…the Edgun pellet skirts are thicker .. im talking about the. 25cal pellets but my .22cal Edgun pellets are totally equal to my .22cal JSB
A little off key here but I thought the edgun Pellets were made by JSB,,,
Just as I was about to buy a few Edgun pellet tins a while back I was informed they were made by JSB ?
Now I am a very very firm believer the right pellet for the right gun is the only way for the one hole group at any distance.
If Edgun is making a super pellet I would like to know…
Oh, and I do not clean the barrel unless I have nothing else to do or I start missing the target, I do not count my shots fired.

On the subject of barrel crowns, I have observed that even on one that is in a less-than-pristine condition, it still shoots as accurate as one without any imperfection. No offense to any of the shooters posting on this thread, but as I frequently state in a lot of my posts/articles, technique is everything in precision shooting. It comes before anything else when attempting to shoot well. Below is the link that takes you to a thread in which I, from time to time, post information concerning accuracy/precision shooting specifically to aid struggling shooters (and even for veteran shooters to contribute to and start a discussion on).

Thank you Jan. :winkn:
Very good description :winkn: of the problem as always Spinj.
Pellet spiraling can be any of or in combination of these:
DIRTY BARREL – Particularly when the rifling on the choke of a barrel gets clogged with lead, the pellet’s flight becomes skewed and is thus angled on its way out of the muzzle. It doesn’t have to be the entire diameter of the choke that has to be leaded, but any particular area of it. Think of it this way, let’s say you are traveling at a high rate of speed with your vehicle on a very smooth five-mile section of a road. Then on the upcoming quarter-mile, your tires roll over a hump that is only a couple of inches high. At that moment, your vehicle is going to launch up for a moment and lose its parallelism to the road. That is exactly what happens to a pellet when it passes over such a part on the barrel.
Some shooters recommend to clean a barrel only when accuracy is affected. The problem with this advice is that you will never know when that time comes. If you’re in a competition or a hunt, you sure don’t want to come across this issue in the middle of the match or when taking a shot on your quarry. Another problem is that the barrel will become overly-leaded that the grooves on the rifling, especially on the choke section, will start to become smooth and flush with the lands. And when you clean the barrel when it has gotten to this point you will need to resort to using more aggressive cleaning methods in order to remove the layers of lead.
PELLET CLIPPING – If using a shroud, the more obvious clipping explanation is when the pellet nicks any part of the baffles due to them not being in line with the barrel. However, there is another reason for pellets to clip the baffles even when they are concentric to the barrel. If the shooter is lacking in shooting technique, especially trigger control and follow-through, a pellet will do this. Here’s why: The moment the pellet exits the muzzle it will nick the baffles when the barrel moves laterally or vertically during recoil. Remember, you need to consider that WHEN USING A SHROUD, THE END OF IT AND NOT THE MUZZLE OF THE BARREL IS WHAT YOU ESPECIALLY HAVE TO ACCOUNT FOR WHEN TRYING TO ENSURE THAT THE PELLET EXITS IT COMPLETELY UNTOUCHED. For this reason alone, lack of trigger control and follow-through is the culprit.
PELLETS FLYING TOO FAST – If a pellet is traveling too fast it begins to spiral or even tumble in flight. The pellets’ trajectory is dependent on the relationship of the barrel they are shot out of and/or the speed in which they are traveling in relation to their weight and/or design.
If you really want to see how these can cause pellet instability during flight or whether your shooting technique is correct or not, you can do any of these two: view a recording of a shot in slow-motion using a scope camera, or fire a pellet at least 60-degrees towards the horizon against the sunlight with your scope set to at least 10X of magnification.
Also barrel polishing could increase shot count between cleaning. :ugeekn: Every barrel is unique one could be “polished” better then other 🙂
This is what happens when lead starts to build up, spiralling guaranteed:
Try to clean more often. 500 pellets is quite a lot. I’m cleaning every 100 pellets for ultimate accuracy. I think Mr.spinj is cleaning the barrel every 50 shots or so….
If you have two guns shooting the same pellet and one is spiraling, take a rod and push some pellets through the barrel of each gun and then compare the pellets. The pellets from one barrel might be more damaged than the pellet from another barrel etc etc…
Another thing might be the pellet is clipping or simply going too close to one side of the endcap and therefore being destabilized
Again, just some speculations of mine :fishing:
Hemn,
I think you have a good starting point by having the same pellet shooting differently from different barrels (in one it’s ok and on the other it is spiraling), so in this specific case the problem seems to be linked probably to the barrel and not to the pellet.
But at the end, should the choke be the problem for example, how are you going to demonstrate this?
Probably this is why often we are saying that every barrel is different and often guns of the same batch of production shot differently.
What I wanted to say concerning the “experts” (without wanting to be disrespectful to anybody) is that probably people like WingMaster or Ernest (just to mention a few), in their quest for perfection, probably have already done some more in depth researches.

Pippo,,,
this topic is only to show the probabilities of the reason and hopefully we can find a solution all together,,, i need to try all my 5 guns to see which one is fussy and spiraling,,,, i also have my friend’s Vulcan and .30cal Edgun with me …. i can bring more guns like FX, Hatsan and AAs,,, and i have lots of different pellets,,, in different weights, brands and shapes ,,, but unfortunately i hardly find myself free …. 🙁 🙁 😥 😥
i rather suspect the choke or crown of the barrel !!

Correct 100% ,,, none of those companies are not able to produce pellets ,,,,
Air Arms
FX
Daystate
Edgun
