TM22 Out-of-Battery Discharge / Case Rupture with Aguila Super Extra – Ammo or Gun issue?

[u/sher-e-punjabb]

Hey everyone, looking for some insight on my new TM22. I gave it a full teardown and cleaning right out of the box. Took it to the range yesterday for the first time and ran a variety of ammo through it: * CCI Blazer * Federal * CCI Stinger * Aguila Super Extra

The CCI and Federal ran fine, but I had a scary moment with the Aguila Super Extra. It "went off" while the bolt wasn't fully seated (OOB discharge). The casing was blown out/ruptured. Since I cleaned the gun beforehand and the other brands ran okay, I’m trying to figure out if this is a known issue with Aguila in the TM22 or if I should be looking at the firing pin/extractor. Has anyone else had issues with Aguila timing in this platform?

Out of battery, certainly gun.
