So something funny happened with the Gemtech Integra. Wolf steel cased ammo runs, basically, perfectly. Wolf Gold, brass cased ammo, chokes.
The Gemtech Integra is purpose built to be suppressed. As such it has a smaller gas-port so as not to be over gassed. However it “should” work with factory military spec ammo. Especially when clean.
Additionally it is not unexpected for low powered, cheap, trashy, Russian, Wolf steel cased ammo to not work well. It’s a known quantity in the industry.
But the inverse is true. Weird. I suspect the Wolf Gold ammo is under powered and not actually M193 MILSPEC
