    Hello,

    Ed, so you have gotten 350gr projectile over 4000fps? What 350gr 416 projectile? What propellant and is it compressed load?

    When I get back to States this weekend we should talk about commercialization status.

    Thanks,
    THEIS

    Just 350 gr jacketed hunting bullet. Comressed load. 300 gr surplus
    ball powder, bullet out in long freebore. Flat base bullet loaded
    way out, in slow twist barrel, real easy to get high speed.

    Got better faster twist much heavier barrel
    coming to do heavy testing for HSM,
    416 barrel here is too light, gonna just do forming
    with it.Commercial, be nice got to figure a way to make
    them faster.If mfg did one there'd be changes to make it
    perfect, or try to make it perfect..ED

    I'm surprised the descriptive name of the cartridge, before ".375 Warner", was .375/.50 - which to me rather assumes that the design has a case approximately the size of the parent or more with a neck down. From the pics and bits and pieces of the dialog, seems this is more of a 375/416 (notwithstanding that the brass is .50 BMG). Anyway, I look forward to the results. BTW, did you consider using the RWS .416B brass - or could you just not resist spending all the extra time making a size 7 out of a size 11? Thanks. Oscar

    It would make no difference in the number of operations to get the form finished and I have a good source for the 50 brass along with RWS primers. When it comes to experimental work like this, I just don't give a lot of weight to incidental costs. If and when we get this to 3700 with good , reliable performance will I even consider making changes. One step at a time. ------

    FWIW, I've thought to inquire about obtaining straight wall drawings with the extractor cut and primer pocket in order to form down to the shape instead of having to neck up first.
    Probably very premature even to think about commercialization at this point.

    I know you're busy but I ran across this reference to primers for larger capacity cases without having to step up to the .50 BMG:

    The new Primer 6,5 mm
    Grillmayer / Ginex

    Hot new rifle primer for medium bores from .338 LAPUA and upwards
    world first in 1/4“ size - new technology in ignition of slow propellants.
    New lease on life for all those .408 - improved enhanced ballistics for
    the new breed of long range cals.
    Excellent for those big African Cartridges - good for minus 41dg Centigrade.

    I'm checking with a couple of suppliers to see if they can order these into stock.


    Regards.

    Hello,

    Those primers are not available, not only in the USA but even international countries cannot get them.
    My last inquiry to their CEO was they are too busy with other primer orders and even if they had the time I would have to purchase entire shipping container for it to be worth their time.

    Maybe they changed their minds but I doubt it....

    Yes we inquired also and was told same and they
    said last Nov, Nato orders would keep them busy for
    at least a year but now it seems for a few years,
    which is one reason we are developing 416 HSM
    with bmg primers. And I wanted to get that
    Ginex primer in the worst way..Ed

    If not longer than that...
    I was just at a Bulgaria munitions company and they are receiving 10 shipping containers per week of NATO approved primers from Ginex, but their order is for 20.....

    Also this past February we tested those Ginex primers at Switzerland facility and their ignition temps were too iradict for ELR...IMO, so we haven't inquired for updated status.

    I know you run (or that it has been done) the 585HE in the Ruger #1 . What would be the max pressure you would say is safe to run the 416HE in the Ruger #1?? I am sure it would maybe not be a good idea to run full bore loads right? Would 50,000 PSI be safe?

    Thanks

    David

    You can run 585, 375, 416 HEs in #! at 65,000 psi, the push on the breech is all the same, the #1 is as strong as the bolt actions we use..Ed

    Thanks for the Reply ED. How many grains does the 416 and 375 hold? Also has there been a 338 version tested yet?

    Thanks
