It's just part of the physics of powder burning ...and some burn cleaner than others ...some are faster burning than others...maybe its a combination of the primer and powder you're using ...extreme weather can also be an issue ( if its really cold especially because it can affect the ignition)...

Hodgdon Clays ...in a 12ga is one of the cleaner powders.....but powder debris left in the barrel is not a big deal...the next wad/shot charge down the barrel ...takes most of it out the muzzle.../ and most of us clean our guns after every range trip anyway...

Sometimes it helps if you list the load, or at least the powder since the question is about powder residue...

Thanks for all the responses. The shotgun I'm using is a Beretta 687 sporting.

My Son whines about cleaning his 687 also. I told him to give it back to me.
John Moses Browning makes a lot smoother finished Barrel in my observation. But they are not chrome lined like the Beretta's either.

What you may be seeing is plastic fouling from the wad. They pretty much all do that.

What shotgun you're shooting has little, if anything, to do with it ...except maybe barrel length ....but most any modern shotshell...completely burns its powder well within the first 15" of barrel length or so...based on what I've read.

Some powders just seem to leave a lot of unburnt powder behind...like Hodgdon Universal in a 20ga ...standard 7/8 oz load at 1200 fps ( I load about 15.5gr ) in that load...but Universal is a little slower than some and for that volume of powder its a little dirtier than most....but in a 28ga - Hodgdon Universal is relatively clean...and I load 13.8gr...in that recipe...behind 3/4oz at 1200 fps...( not a huge difference - but in the 28ga, it seems to burn more completely )....

No, not without knowing what your reload is. Its kind of a guessing game. Give us a clue.
