Host is a CZ Scorpion SBR (7.72 barrel) with a tri lug adapter. Suppressor is SiCo Hybrid. Shot about 60 rounds and metal shards came out of the first baffle area when I took the can off. Ammo is Winchester 115 grain FMJ value pack.
I don't see any baffle strikes. What would cause this? Bore has no obstructions and is smooth. Would a suppressor (velocity) have any impact on this? Or is it a AMMO issue? Attached File |

If you have jacket separation without a can, there's no velocity behind the fragments. They'll just kind of flop out of the end of the barrel. No velocity means they won't fly forward at 1050 feet per second, so no visual signs on paper.
However, they can just kind of fall out and land in the can... so most likely, ammo related-- and it was probably happening without the suppressor as well, just no way to see it. |

Quoted:
I'll try different ammo and see what happens. That makes sense about the metal shards having no velocity. There are no signs of impact on the first baffle. |

These days, a lot of the pistol ammo does not have true jackets. Instead it is a cast lead bullet with a fairly thick copper plating. This is especially true with the "white box" generic and slightly less expensive ammo and in most projectiles used for reloading. The plating is not as thick as a true jacket, and in a given lot the plating may be a little thin, a little soft, or even not sticking well to the lead substrate.
On the other hand, it makes the EPA Nazis happier in that the heat of friction does not melt or vaporize the lead core as would happen in a plain cast or even a swedged jacketed bullet that has a bare base. |
