It's hard to see what it is but looks a little like un-burnt powder.

What kind of powder did you use in your reloads?

 

HS-6. Was my first batch of reloads, shot well except for one stovepipe. First malfunction ive had with this gun

 

What was the charge and bullet weight?
Stovepipe may be caused by a low(ish) charge which also would explain the unburnt powder.

To be sure, clean the gun fire the Armscor, check for flakes and if not present shoot your own loads and check for flakes.

 

From what I can make out, it looks like unburnt powder as well.

 

I have zero worries for your gun. I would do what was said above and shoot some factory ammo and check it.

 

I suspect the Armscor ammo. I have noticed the same thing after shooting the Armscor ammo in my 22 mag pistol.

 

Thanks everybody for the replies. My load was 124 Gn Plated bullets with 6 gn of HS-6. Decided to go to the next load in my book which is 6.4, and ill see how those shoot. Ill also try to narrow down whether it was the armscor or the reloads that was causing it. As long as it isnt metal shavings from my gun that is good news lol

 

Do the flakes resemble your powder?

Decided to go to the next load in my book which is 6.4,

Just a side thought, why not load up 10 rounds of each of the loads you're working up? It would save materials and if a load shows signs of overpressure you won't have to disassemble as many.

 

I've often found lead flakes in my guns after shooting hard cast bullets. Could your bullets be leaving such flakes that are "scraped" off as the bullets enter the barrel grooves. Tinker with the flakes with a needle and you might find they came from the bullets, quite a natural occurrence.

 

If a 1911 is rubbing metal together so significantly to leave visible metal flakes or shavings, it won't be running right, or at all. Looks like Unburnt powder to me as well.

 

Is it my eyes or is it flakes of brass from the cases?

My camera kinda turned it a little orangeish/redish, but it definitely looked more like gray or silver flakes in person
