    I did a quick reading on that article, and it deserves surely a through reading, but first i am off to CHRISTMAS dinner with the whole family.
    Any info is welcome.

    To make it up for my lazy Sunday afternoon here are some crushed numbers from Celsius to Fahrenheit.
    First row of the table is the metal, second row is melting point, third row boiling point, fourth row vaporizing point

    My foundries can go really high.
    The small one and the big one are both up to 2282F, max
    The "master" 4172F, max
    The lead pot on propane 1380ish, max.
    Thats why i was intrested in the boiling and vaporising point, and other things to (sand) cast
    When somebody wants to melt at those high temps do it in the wind!!!! Better save than sorry and put a gasmask on, not a p3 dust filter!!!
    Even with some metals wear eye protection because of the uv radiation, i am not kidding.
    Dont fool around, or put cold metal in a hot metal, be safe and enjoy, pleaaaaaaase!

    pressure plus speed is equal to friction
    hardness, surface friction and diameter is also important for bullets, even important as bearing metal alloys.

    But this is all nice theory, i really hope for some feedback before i start melting some metals.
    Any help idea or thought is really appreciated.
    Popper again, good article.

    And now my gents,,,,M E R R Y C H R I S T M A S S

    Anybody use this for high speed hunting or would they recommend it?

    That is close to what I make/use, works well. Knocks down steel @200 yds, ~1700 fps at the target, didn't pulverize - only found a sliced off sliver, still had some PC on it (hit the edge of the plate). Don't think it expands much. Did get a 120# ish pig, tail to jaw, broke a leg & jaw. 165gr 40XDm @ 25 yds., ~950 fps. Hit another pig with 185gr (same alloy), BO pistol but never found the pig.
