Lee Breech Lock Pro

[cheech]

I’m unable to get my universal casefeeder to reliably feed 223 cases without the occasional double or triple feed. There’s a video on YouTube of a guy having the same problem with his Pro 4000 so you can get a look at what I’m encountering. The casefeeder is set up correctly and I made sure I’m using the small port but, nothing I do will stop it from double or triple feeding cases. I now just manually insert the cases when the ram is at the top of the stroke. Is there something I’m overlooking or is there a tweak I can try? The casefeeder works fine for my 9mm and 45 ACP cases.
