White Residue

[Kagnew]

I've noticed that some factory ammunition tends to leave a white residue on the feed ramp and around the breech on my pistols. Is that unburned powder, or coke, or what?

Whatever you do .....DON'T try to snort it

Shiiiiiii', man. That was good stuff!

Okay. Straighten up. Any ideas?

Lead bullets? Dark color finish on the feedramp? In all my years I've never seen ammo leave a white residue on a ramp. What are we smoking today? (just kidding) It could be anti-matter. WHATEVER YOU DO DON"T LICK IT!!!

Right!

No, it's a white residue on the feed ramp and around the breech. Even some down into the trigger mechanism. I've noticed it when shooting Magtech FMJ (in 9MM Luger, .380 ACP and .32 ACP). I can't figure out if some partially-burned powder, or what it is. (I did have a squib, the other day, with a Magtech .32 ACP round. The case was still half-full of powder, and the bullet was about half-way down the barrel. Weird feeling when you expect to hear "bang", and only hear "pffft!") Maybe it's time to switch ammo.

If its on the feed ramp and breach it seems that it must be something on the cartridge that it there before you fire. I'm thinking the cartridges may be coated with wax or lacquer.

maby take some steel wool to the cartrages to see if its coated. if not, did you check for a punctured primer?

 

[Drail]

Yeah, I would clean the snot out of it and avoid Magtech. I've heard some complaints with their products.

Steel cases?

I have shot thousands of rounds of Magtech with no issues, and I have never seen any white residue when cleaning.

Steel cases?

Nope. Brass cases. It does have me wondering, though, about some sort of coating. Maybe I'd better swear off Magtech.

I had, too. This just started happening recently. Maybe some of the boys in Brazil are in cahoots with their cousins in Colombia.
