I'm going to order the Inline Fabrication case ejector system for an RCBS RockChucker to speed up brass processing. Does anybody have one of these? Are there any quirks a guy needs to be aware of? Anybody used it with a press-mounted swager?

I use one on a rockchucker, I don’t do any swaging with it though. It’s a great addition, very happy with it for 6.5 creed and shorter cartridges. For quirks, doesn’t work as well with longer cartridges - seating bullets, when the ram is high enough so that the spring slides off of the case there isn’t much room to fit a bullet on the case mouth

Overall, saves quite a bit of time if single stage reloading

You will love it.

The case kicker speeds up a single stage press so much it will change your reloading.

I have them on my Redding Big Boss II and the T7 Turret. Aces.
