I was at the range today and got ready to shoot some factory Federal 224 Valkyrie ammo (mainly to recoup the brass since it’s wildly inaccurate), and I had a big...event.

When I pulled the trigger, a strange bellowing report sounded and a massive fireball erupted from the suppressor and the ejection port. Like a HUGE one. If I was a lefty, I wouldn’t have eyebrows or facial hair. I dropped the mag and safed the rifle and inspected the chamber quickly, nothing unusual.

I was expecting to see the front of my suppressor missing and mangled. It was intact and not a mark on it.

I removed the can, and keep in mind I had cleaned the suppressor since the last time I shot it, so it was spotless. The blast chamber was FULL of crud. There was debris everywhere.

The brass showed zero pressure signs at all, and nothing unusual to speak of.

I think it somehow it had the wrong powder in it.

Glad I was wearing eyepro.

Any thoughts?
