    Since Australia has become the land of Retarded gun laws by the Fun Police, we are always looking for new ways to hunt pigs....And i think we just found it....
    So whens it going into production?
    And when do i get one?
    And is using a screw in flash tube possible to use magnum primers.. ( BMG primers here are next to impossible to get )
    Failing all that, sell drawings..... Id pay $100 for a set....
    And try a projectile like this.....
    And i cant load a pic of it off my comp????? hmmmmm

    i am in the process of designing a bolt action version that will hold a total of 3 shots. we will see how it goes lol.
    It's not the size of your brass that matters, It's how you tumble it.

    I have two Fisher Mcmillan Shell Holders sitting in the USA with nothing to do since they banned 50's in my state...(QLD AUSTRALIA)
    What would you charge to chamber and fit two barrels 16.5 inches long, fit two Fisher muzzle brakes?
    I was thinking about the 50 spotter necked up too .700 and making a swage die set make a jacketed .70 cal version of a .45acp Federal Hydrashock projectile.. I made a mold for a 12 ga version that weighs 660 grain (that was the pic i was trying to post)
    And do you have a private email address?

    Hell of a gun.
    I just got through watching the Youtube video of you shooting the high power load. Man dont try that with out the brake!!!
    Do you have a rough idea what the chamber pressure was for that load???

    Cheers and Good Luck

    I just had the same impression. I'd fire one shot at the range and wait for the flock to gather. That is a muffin slinger right there.

    What powder are you using in it?
    Are you using BMG primers?
    Or making thread in flash tubes for Magnum rifle primers?

    im using 50bmg primers, best way to light 200grs of powder lol. right now my current load is using 195gr of 4831SC and a 1132gr paper patched boolit. im am going to work up so loads using W748 so i can get my pressure up in the high 50k so i can get a cleaner burn and more velocity from it. also by my calculations i can get less muzzle blast by lowering muzzle pressure. i will do that by reaching max pressure sooner in the barrel and getting a more complete burn.

    Nah, we are talking about innocuious (sp) naming here, "Daisy Cutter" comes to mind.

    Although I think JT may be on to something with the newer generation and all this texting and what not. "***" fits. If it ever get's to the manuals more than a few will be the same way....***?

    What materials did you use for the bolt and receiver, and what heat treatment did you apply? Did you send out the parts for heat treatment? Any estimates on chamber pressure and/or bolt thrust? I've started drawing my own bolt action with the help of the Ottenson books and some actual firearms engineering texbooks, but I would love some info from somebody who has the "hands on" knowledge from such a fantastic project.

    I would do the job for one of the rifles in trade. That would mean no money out of your pocket for the conversion. but i don't know how shipping of the gun would work.

    I think your next direction could be one in a Speciality Pistol!! Fire that one handed!

    Very interesting. Have you gotten any game with it yet? coulda used that when the elk were trying to run me down a couple of weeks ago.
