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
