That is seriously weird.
i don’t know what the configuration your shroud is but if is like mine, there is a tube with a tube, I am wondering if that has come looses slicing lumps off the slugs before they even get to the mod. Is the barrel nut concentric to the mod, is it the right calibre.

Yep, back warranty! It's configured just like yours bucket, liner-sleeve-shroud-donny fl. No scraping/lead build up on threaded barrel nut,nothing loose? Have had barrel out, everything’s in alignment as I can tell????

Just to be clear on what we are looking at. That’s lead on the outside of the barrel liner?
If it is then the lead has gotten between the shroud and the liner?
Is it possible a pellet was accidental dropped between the liner and the shroud when the gun was assembled and it has nothing to do with the shooting of the gun.?

It’s definitely lead!,good point though wondering if it’s possible that the o-ring got rolled over and dispersing lead past the o-ring? Not sure how that’s possible without a lot of back psi at end of shroud or Donny fl neither showed evidence of restrictions?

There's really no way lead should be able to get in that part of the shroud if the barrel is seated in the action correctly and threaded correctly at the muzzle. That's Crazy!
Was everything attached correctly and the threads tight at the muzzle?

It looks like it's actually lead dust collecting and mixing with silicone lube used in the shroud for the o-rings when you remove the shroud. I get lead dust in my fixed shroud, but it isn't lubed much and so it doesn't mix, but I do notice it does get "grippy" with dust build-up if I don't take it off for cleaning on occasion.

Everything as should be as far as I can tell no expert though with FX impacts! But I have been washing and lubing pellets usually don’t do this with other guns I have don’t know why I started now? Lubing with a very small amount of silicone! Good observation airgun hobbyist! Still puzzling? Thanks Guys!

IMO its just an excess amount of lead buildup within the shroud. Then when you remove the shroud it all gathers and smears because of the o-ring within the shroud. I've seen this happen just not to this extent. The good news is this is proof that the shroud with the air stripper is in fact working! The question is why so much lead? Clipping of shroud, clipping of silencer (LDC), extreme velocity disintegrating the pellet? Which projectiles & what's your velocity? If you're slinging soft lead pellets at a ridiculous velocity, then I would expect this buildup to be normal, and the simplest solution would be to reduce the velocity. Otherwise, here's what I would try:
- Clean outside of barrel & inside of shroud (including o-ring) & muzzle area (to help detect clipping)
- Reapply a tiny bit of silicone to help shroud glide onto barrel
- Reinstall shroud
- Shoot with shroud only (no Lead Dust Collector)
- Do you still have fliers?
- Remove shroud & inspect for buildup & clipping
[/LIST=1]
You may also try just shooting it with LDC (without shroud)
- Clean inside of LDC especially muzzle area (to help detect clipping)
- Shoot with Lead Dust Collector only (no shroud)
- Do you still have fliers?
- Remove LDC & inspect for clipping
[/LIST=1]
Curious if this isolates the problem, and what you find.

Well here’s a theory, first let me ask if there should be a o-ring inside the shroud where threaded end of shroud seats against the barrel nut? What I think might be happening is lead dust is leaking past the flats of the barrel nut dispersing lead dust back onto the barrel sleeve? That would explain the lead on only 1/3 of barrel sleeve? But why is lead getting there in first place? Ya guy’s I’m stumped on this one, I looked at my RW and a little lead dust on barrel “evenly spaced around circumference” plus it’s a different style of shroud/diffuser.
No the o-rings only go on the liner which is inside the barrel housing (some call it a sleeve). The shroud has an air stripper and is ported to redirect air back into the shroud (& on top of your barrel housing/sleeve).

No o ring on the thread but I had another thought that might explain the lead shaving at the erratic groupings.
is the mag, the pellet probe or the barrel transfer port shaving off lead as the pellet is loaded? The pellet leaves the barrel but the back pressure causes the shavings to accumulate over the barrel.
Try this... remove the buddy bottle, load a pellet into the mag, with the cocking leaves load it into the gun. Remove the barrel and with a cleaning rod puts the pellet back out of the breech and inspect for any damage.
If everything seem ok, push the pellet all the way through the barrel to see if there are any issues.

Thanks Michael, I’ll try those suggestions for longer periods of time isolating each variable, just so you know only shooting jsb 18.1 @ about 900fps, tried some hades @ about 960fps only about 50 pellets though! Thanks also Bb will try your’s as well, problem now is going out of town for the holiday so maybe a few days before all this can take place!

You may also want to polish your barrel if you haven't already. I have had some barrels and liners that have taken a few rounds of polishing before I started seeing less lead residue and tighter groups.

I thought maybe I should try to, there seems to be a lot of leading at the choke?, I have some jb bore paste and bright might give it a “ “whirl” ha,ha never go across the direction of the lands...
