I bought an old, like new RCBS JR2 press a few years ago. It came with a automatic primer feed, which included 2 brass primer tubes, one for small and one for large primers. MY question is how do you load the primers in the brass tube ? I tried to put the tube over the primers, but as soon is I lift the tube up to grab another primer the first one falls out back on to the primer tray.

There should be a small cotter key that fits in the hole at one end of the primer tubes. That key should be in place when you load the tubes. The end of the tube that doesn't have the hole for the key will have a C-clip spring thingy on it.

To load the tubes, you place the primers on a hard surface, shiny side up. A primer flipper tray is ideal for doing this and will orient the primers for you. Then just press the C-clip thingy end of the tube over the primers one at a time and they will snap in and be retained in the tube by the spring thingy. When the tube is full, invert it and insert the Cotter key end in the primer feed attachment on your press. Then pull out the Cotter key and the primers will slide down and be available to feed.

wild hobbybobby, Thanks, I tried loading some primers in it But not quite sure how the tube holder is to match up with the primer cup holder? Some would feed and some would not.

My first press had an auto priming system on it and I have never been a fan of this and have much preferred doing it with a hand priming tool. If it gives you too much trouble, I'd do it that way.

M1GARAND I have to agree. After messing around with it I got it working fairly good, but it still did not seem like a good priming system.

Lyman invented that press mounted tube fed primer system in the early 60s and their's worked pretty well. The RCBS copy never seemed quite as reliable.

Lee came along with a good working tray fed hand primer and the other systems lost so much market share they were dropped.

I have a RCBS hand held primer, the older one, it seems to seat the primers alright, but sometime it just doesn't feel right when squeezing the handle.
