I'd like to see/know more detail?
What length of barrel?
What's the load data?
How many rounds on the barrel?
How many rounds in between cleaning?
Let's start there.
I'll question the load. 2880fps out of 6.5CM.... in my opinion that's stepping on it and not a normal max working load.
I'm running the 153's at 2700fps and I'm going to tell you I'm at a max load every day working load.
Later, Frank
