    Roger that - especially with carbide die - just enough to eject with reasonable effort.RG

    Seriously, on Georgeís advice, I followed your method. It takes some careful measuring and patience, but it works.

    And then thereís the right punch diameter. ........darn, where did I put that chicken foot.
    Yeah - I wore out a few rabbits feet, crow skulls/bones, and rubber chickens!
    George makes great dies, knows how to, "get it done", and is very generous in sharing his knowledge. And it's repeatable!! I do like the OPs (OliveOil's) concept, which would be pretty good for, "getting close" - I never thought of that! RG

    Gentlemen,

    Thank you for all the above information and your patience in understanding my poor English.

    I fairly understand what I would call a "final result" in your explanation about irrelevant measurements and cored jacket staying in the die and all the "classics".

    I will be a beginner in bullet making within a few weeks. So I do not have (yet) a core seating punch collection gently waiting for use.

    At the moment, my point is to "come close" to the true core seating punch diameter to avoid to much trial and error and multiple machining/honing/lapping cessions to reach the right punch dia.

    I am lucky enough to have a barrel that shot 135 gr and 124 gr with great success, so "reverse tuning" by going to 122gr or 126g should not be a problem, if needed.

    I am not dreaming anyway. Next jacket batch, next 2 or 3 new core seat punches and so goes the collection on ...



    Mr. Robinett :

    I still remember this night (my time) we partly spent on the phone when I was having trouble with my HBR gun / seating Burger bullets. That was in the early 2000's and I was probably the first to import your .30 10cal 124 in Europe at that time. That was through Sinclair, and that was in the Good Ol'Time, even if some French bullet maker (7 O) threw me stones beause I was breaking his retirement plan.

    Did you know your bullets take age like a good French wine ?? Due to work, I had a loooong BR break, but in 2016, I blowed the dust off the boxes and shot a second place at France Championship 200 meters stage. Thank you !!

    I already PM'ed Mr. Ulrich. He was very kind in his explaination and will send me some additional info.


    As far as I understand Mr. Schmidt #14, there is a "RG's Special" method to "come close". I am very much interested, you bet.

    Just speculation but I believe he's working on a mechanical device other than a press to seat cores.

    Somewhere, I've got some pics of some strange bullet swage contraptions built by Ferris Pendell, featuring all sorts of gauges and dial indicators in various positions . . . measuring deflection, pressure, who knows what - maybe I can dig them up - they sure don't resemble anything we use these days!

    That slick little ram assembly Javier Bardem carried in "No Country For Old Men had about a 1" stroke......

    Pneumatic slaughter gun / stun gun used in slaughter-houses. But 1" stroke for a 1" jacket is a tad on the long side ...

    its all on the line on jacket and its release out of die eyes and feel

    Process control does not come from "feels".

    Ask Motorola and 6Sigma. If a process result is not in line with the measurement of a process variable change, then the choosen variable most probably is not the right one.
