Question about Sinclair Priming Tool

[South Pender]

I've run into a conundrum regarding my Sinclair priming too. Mine is a stainless steel tool that I bought maybe 10 years or so ago. I have used it with the head that takes Lee shell holders, and I have several shell holders for different cases.

Recently, I ordered a couple of Sinclair heads that are one-piece--i.e., not requiring a separate Lee shell holder. They seemed better than the heads I've been using. When I received the heads from Sinclair (Brownell's) they would not thread into the body of my priming tool. The threads are slightly different from those on the head I've been using (with the Lee shell holders). However, when I look at the Brownell's webpage with the priming tool, my tool looks exactly like the current stainless tool they are selling (and which, presumably takes the one-piece heads).

So can anyone here clarify this puzzle for me? Did Sinclair change their stainless steel priming tool at some point in the last 5-10 years--putting different threads on the tool where it takes the head?

At the moment, I'm stuck with the two one-piece heads and no body to screw them onto.

You need to use a thread gauge to determine the threads on the holders. Try to determine the threads on the tool itself either by measuring one of the old components, or with the thread gauge. Then turn up an appropriate sample from aluminum to verify the measurements and check that it matches the tool threads. I would guess that the new holder has thread specs that are not the same as the older tool.

I had to modify my recently acquired Sinclair tool to adjust the seating depth by a few thou. This was an easy fix in the lathe since the seating was just off a bit for my brass. Now it works perfectly for priming my 338LM.

If they won't screw on the body, call Brownells/Sinclair and ask what is going on. If no joy, send them back.

yeah your question needs to be directed to Brownells/Sinclair

I had a similar situation occur with their case trimmer when I order a new carbide cutter, the cutter wouldn't fit the barrel of the trimmer. I called them and they replaced the barrel free of charge. They're good people to work with, a least that's been my experience.
