I know it's like a Ferrari towing a Hyundai but I've had great luck sizing bullets with my Lee APP.
I have a Mr. Bullet Feeder that I have hanging from a 3/4" black iron pipe instead of off my Dillon case feeder. Among other things, it makes it a lot easier to move. I'm going to bolt down another black iron pipe and mount it next near my Inline Fabrications Quick Change Mount. The idea is that I can slide in my Lee APP press that I size bullets with and instead of using tubes. I can easily move my MBF and use it.
At least that's the idea. I'm wondering if anyone has hooked up a Mr. Bullet Feeder to a Lee APP here? How did you make the connection? I was looking around and I didn't see anything obvious that other folks had done. Although, I know many have done it. It's not rocket surgery but I'd rather not do something worse if someone else has already done it better.
