Ive owned every edgun but the L2 , I also owned most brands , I have had pellets spiral with some guns threw years ,here is my input causes and cures and things it wont be ,
1. shoot gun with no moderator did this fix it ?
2, a dirty barrel can also cause it clean properly
3, barrel issues like crown or bent or not true bore , I use pellets with a cleaning rod push threw with similar pressure and harder at choke if it is loose and hard it has a flaw ,minor flaws can be polished
4, it wont be a reg setting only inaccuracy would be if its too fast and you are not this issue
5,any misalignment like mag to breech , or muzzle to moderator , but we said shoot with out moderator should rule out the muzzle end ,
6, if it is like 1 flier per mag is it always same index point? like a mag needs to bee enlarged ( I had guns threw years where mags needed to be tuned where pellets needed to be honed so they fell threw by own weight when orings were removed ,
7 clipping
also what I did not mention is did you test a variety of ammo and head sizes , But my edguns were never ammo picky like some other brands .
If all this fails messege ED or BRIAN , any issue you have they can help you get it sorted out , all edguns I owned were durable and reliable but time to time like a car something may have been gotten by qc or damaged in shipping .
Can the L2 be shot with out a magisine to rule out things ,
with an accuracy issue it magnifies the farther you go ,
I have a few ,22 cals which hate the 25 gr jsb and I attribute this to twist , I am not saying this is your issue but saying I know what a spiral is , I got a pcp not a edgun shoots 44 gr lazer but 50 gr sprial but it shoots slugs to 60 gr , I just dont use 50 gr in this gun ,
I hope something I said helps
I will follow post as I like to know solutions for my own understanding for future knowledge.
oops this is older thread I failed to notice before relying
