What is this white powdery substance on barrel?

[taseal]

It's not exactly reloading, but This is happening after my reloaded rounds. I think it's related to unburnt powder from my lower charges? I'm not too sure.

but inside the barrel has this faint white powdery substance and then when I use a bore snake, it 'puffs' out of it...

I have no idea what can be the cause....

any ideas?

watch in HD (720p) you'll probably see it better...

My advice is to dump the bore snake . The best way to clean is with a good stiff rod like a Dewey and proper bore brush , patch and jag with solvents like Hoppies BR or Sweets 7.62 .
A bore snake can not scrub the bore properly.
I am not sure but I think the white residue may be from the bore snake . Anyway pulling it out the muzzle like you are will eventually wear away at the crown and damage accuracy. If you have to clean from the muzzle then get a barrel bore guide and a rod.

I've noticed that too I just figured it was ghost turds... Now I run at least 1 wet patch after a range session and dry patch it out before the next.

No biggie mate, it's Carbon - think of it as the ash residue from your powder.

Ah, I thought carbon would be black, not white.

and I really doubt bore snake is going to damage the crown. It's just a mild brush attached to textile material?

"I thought carbon would be black, not white."

White 'carbon' IS a novel idea!

I don't use Bore Snakes and I haven't a clue what white stuff you're seeing might be...you're in south Florida, maybe it's termite poo!

Any repeated rubbing at the muzzle will eventually wear it some and that will indeed harm accuracy. Pulling straight out will reduce that wear but that's virtually impossible to accomplish perfectly. Even so, with modest care, it would take a LOT of dirty Snake use to polish away enough steel to make a difference. I think.

If you go back to the sand box look out for my Marine grandson, he's a good kid but kinda clumsy!

Powder ash. No problem.

It's the stuff that makes a bore patch all shitty, until it's all out.....

I don't like bore snakes either, for anything other than a 12 gauge shotgun, but ripping on the guy about muzzle wear then telling him "regular" brushes and patches won't do it is not logical; re; stupid.

Repeatedly push a brush out of a muzzle, because they won't turn in the bore, and it's doing the same thing as a boresnake.

That's what I was just going to say....

how can a borebrush hurt, but not a rod/brush?

I will say I realized it didn't clean it around the rifling well.

oh well, brownells is on backorder on bore tech eliminator and I want to get everything at once from them, so I gotta wait until all that goes back in stock.

The cord on a bore snake will pick up grit , carbon and primer residue an act like a file on the muzzle crown over time the way he was using it. NO one was "Ripping on anyone except maybe you " I was mearly pointing out that a good rod and brush from the chamber end is better than a bore snake from the muzzle end at cleaning properly. A rod and brush used from the chamber end will not harm the muzzle . It is an totally different process. You can believe what ever you want.
