I use often PTFE powder alone as a lubricant. Often for 3d Printed magazines and sometimes after cleaning my rifle barrel - I add a small amount to my tin of slugs. Prevents led fouling for a long time.

But a mixture of all three above will give long lasting dry lube.

I pulled the huma spring out and ran stock spring with the huma hammer kit. Swapped it Fri and used a tin off pellets no acting up. Just a fyi

Normally it is a problem derived from adjusting trigger too far. Give a quarter of turn counterclockwise.

My FX Crown Mk2 was doing the exact same thing after less than 100 shots with the as delivered tune. It has a dealer installed FX slug kit with the tungsten hammer. The trigger screws were all secure with no sign of movement. When I removed the trigger, the top of the trigger and safety were covered with fine aluminum shavings. I could see the front surface of the spring holder crown (part D3) had a very rough surface and most likely was a source of the shavings. The rifle was returned for repair where it is waiting for parts. No word on the cause.

I had something similar happen with my Crown. I removed the heavy weight and use just a Huma spring and pin probe.

Scotty, what was the source of your aluminum shavings?

Scotty, what was the source of your aluminum shavings?

Mine were brass shavings from a hammer weight. Check your hammer spring ends, mine were burred and sharp and were scraping the brass weight. With only the pin probe and Huma spring, I was able to get enough from my Crown.

That is starting to make sense. I didn’t disassemble the rifle any further before I returned it. My spring was probably broken on the other end and created aluminum shavings instead of brass.

FX is sending my Crown back today. The sear was broken (spring was just fine) causing the trigger not to reset and the sear to drag across the hammer when cocking. The metal particles came from the hammer as it drug across the broken sear. Mine was one one of two FX rifles in for repair with the same problem. Hopefully the new sear doesn’t have the defects of the original. Test targets still showed 1/4” groups at 50 yards.
