I like my auto prime!
I use the Lee auto prime XR. Sure Lee stuff is kinda cheap but it is what it is. I enjoy it and find it to work quite well. Like others have said I load in small quantities and priming is pretty quick that way. I have a ram prime set up for my classic cast haven't used it and may not ever. Who knows. To the OP I couldn't agree more about using equipment that was passed down. Cherish it and use it! I'm the same way!
