Thread: Screwdriver Boolits

  1. #1

    Screwdriver Boolits

    Does anyone know of a mould for screwdriver boolits?

    It seems to me that hard cast boolits of this style would work really well. Soft hollow points don't always like to be smashed into a feed ramp, but a hard cast boolit of this design should be easy to churn out and wouldn't deform on the way into the tube.

    I can already see the challenge of mass producing these the traditional way moulds are cut, but with today's CNC machines it should be possible. I'd pay more for something of this design.

    There was a fellow a few years ago who went a bit further with outrageous tips on cast bullets, one was an actual screw. Maybe someone else remembers his handle or look in the archives.

    frustrating...I remember seeing those and more like them but my search efforts have failed miserably.

    That’s an interesting design. I guess it is supposed to open up like petals of a flower. Have you ever looked inside one? Is it a solid lead core or is there possibly a hollow point under the jacket?

    As I remember he was a retired machinist with a CNC mill doing the near impossible. I think there were 2 Threads with lots of pictures. I looked too and didn't find them. They might have been in Castpics.

    Take a guess, how much do you think that profile would cost in a mold?

    It doesn’t open at all. Instead the scallops create a wake effect in ballistic gelatin (and presumably meat) that is supposed to incapacitate via hydrostatic shock. It all sounds very hypothetical to me and I would want to see a ton of evidence from real shootings before I went that way on carry ammo.

    Yeah… that video doesn’t make me feel any better about the design for self defense…

    Interesting. Thanks for the explanation.

    I think the best way to make a mold for this profile would be with an EDM system. And I wouldn't chose it for self-defense unless I lived alone in the deep woods. WAY too much penetration for soft targets like humans. I'm in town, got neighbor's houses within 10 feet mine on one side, and about 20 on the other. I mostly like my neighbors, and wouldn't want to be penetrating them.

    I remember reading that those were designed for the “Second Chance” pistol matches where the winner is the one who clears a table full of bowling pins in the shortest time.

    Of course, the gamesmen went after this as soon as it was set up. Hollow points filled up with wood, and didn’t expand enough to make a difference over solid flat points. More power was not the answer, either. A Magnum load might knock a pin off with a marginal hit, but a center hit would splinter the pin, and splinters on the table count as pins and are harder to clean off.

    So that Phillips design was devised, which (theoretically) would twist the pin off its base with any reasonably solid hit, and hopefully roll it off the table.

    You’d need a special (and expensive) nose punch on a swage die to make that design work in production.

    We Know Mass Cannot Be Weighed But It Has Newtonian Weight And That Is Derived From Kilograms And Kilograms Can Be Converted to Pounds. But, Still Mass Cannot Be Weighed. But How is the kilograms obtained? Can Kilograms Be Weighed? Evidentally Yes It Can. But, Still Mass Cannot Be Weighed So Kilograms Must Not Exist. Funny Isn't It.
    One good thing out of this the next time I'm at the doctors and they want to weigh me I'll tell them mass cannot be weighed.

    Interesting!

    Is the dollar plus per slug their standard or panic shortage price?

    The bullet in the OPs image is monolithic and doesn't expand at all. The flutes coupled with the spin of the bullet force fluid outward when it strikes tissue, but it'll penetrate through intermediate barriers without much deformation or loss of terminal effect.

    That sounds close to the price they normally are.

    I just use a Hard "hard cast" bullet with a very decent flat meplat and don't worry about it.

    I suppose nothing will, but I mainly carry a .32 or .38 snubby so hollow points aren't that reliable either. Wadcutters my be the next best choice but this design looks very promising and I'd like to cast them for pennies rather than buy solid copper boolits for a few dollars each.

    What might be desirable would be a reduction of metal in the front of the bullet to reduce penetration but too much would make the bullet too fragile for feed ramp impact when cast of lead versus the same in a copper alloy.

    Look up “Xtreme Defender.”
