Dillon makes carbide dies and the 223 is available in carbide. You do not need to use lube but I give a couple spritz of Dillon case lube.
I have had 2. 550’s, 1. Square deal, 5. 650’s.
I prefer the 650’s especially loading pistol cases.
Hand rotation leave a possibility of a double charge in pistol rounds. Also avail is a lockout die which is a added safety measure. I wouldn’t wait until he returns, get it now and learn to use it. It will make loading with your Grandson more
Pleasurable in my opinion. In that time you will become proficient and be able to teach him the ins and outs of the press.
