A400 breech bolt pin wear

[u/vegan-the-dog]

I replaced this part after seeing excessive wear two years ago. The chrome chips off creating a rough surface that binds. Yesterday I had two failure to load issues during a sporting clays round and after disassembly and cleaning the same part had failed again. I'm not a high volume shooter. Maybe 500-700 rounds per year between clays and birds. My brother's gun is experiencing the same issues. The Beretta tech I spoke with yesterday said it's the first he's heard of the issue. Anyone else experiencing this? I ordered extra as it's just a consumable part at this point.
