At the range yesterday throwing a few hundred rounds through it. I noticed the ports had all sorts of crap in them afterwards. Almost like lead getting scrapped off each round. I was shooting Winchester FMJ 115gr.

Here is the first probably stupid thought that went through my head.

""The jacketing is coming off the round in the chamber.""

Cleaning was normal. The barrel looked fine after brushing it out.


I guess I am just wondering, what I should look out for, avoid, do...with this Ported 9mm.

FMJ is not TMJ; the base of a FMJ bullet is exposed lead.

Lead gets vaporized by the powder ignition, and when it cools, it solidifies.

Just get a good brush or a dental scraped and remove it. No big deal.

To avoid it in the future, use a TMJ round such as Blazer.

Excellent. Sounds good. I know enough to not shoot reloads or non jacketed rounds. The FMJ, TMJ thing I did not know. Thanks for the 411.

Just curious. Why ported?
The V-10 comes factory ported. The porting lessens muzzle flip and recoil.

I agree with cuda66, it's lead and unburned powder. Same thing happens in my original V-10 and my Taurus 617. Get a brush, some Hoppe'sm and clean them out.
