Yep. Test it on a 308 case or a 243 and see what you get. If 308 does nothing maybe the 243 will get a 7mm neck.Maybe a expander die. Are there any markings on the top? Does it come apart?
That makes sense to me, but based on what the uncle loaded, doesn’t make sense. Will see if I can measure the rod and see if I can figure it out or maybe that will help identify it. Thanks for the inputLooks like an expander die to me as well.
It has been tested to give better consentricity than an expander ball. It also works good on necks that have been stepped on.Ok. I just mounted in press. Have some new .243 brass and a bullet would not enter mouth. Ran brass into this “die” and it did indeed expand mouth enough to get bullet started, couldn’t push it in by hand, but see if I used bullet seating die, it will go in without issue. So if this is what it is(expander die), why would you need this if when you resize the case you would be expanding the mouth anyway? I can see that with the new brass that was with all the stuff I got, this would allow seating bullet and loading without using the sizing die, but I generally size all my brass anyway. Am I missing something here?
Expander die body with expander. No markings on my die body either, just the diameter on the mandrel/expander.
New style and old style Sinclair in the pics.
Thank you, thank you. That’s exactly what it is. Went back after seeing your pictures and moved the lock ring and there was the other set screw underneath. Loosened and the rod came out. That now explains some other parts I found.Expander die body with expander. No markings on my die body either, just the diameter on the mandrel/expander.

I just bought a bundle of reloading supplies from a friend. This was included but have no idea what it is. Other items in stuff I got was 7mm REM mag, .243win, .270win, and .220 swift. View attachment 1145245View attachment 1145246View attachment 1145247
