More LEGO Bullet Testing

Last month I test fired some LEGO heads out of my .40S&W Glock 35 Gen4.

A few days after I posted that article, my friend Joel helped me reload some with some gun powder. As many had surmised, it did not work in cycling the Glock. However I wanted to test it and here are the results.


Well this phenomenon has been picked up by Taofledermaus and he had a friend test lego heads as well. They used a chronograph and got over 400 fps as well as some decent penetration into clay.

In the video below, you can hear Ron mention the Spider-Man Lego Head is 19gr. Lego heads are only 8.5gr. I commented on the video and Taofledermaus said lead shot and epoxy was added but he did not find this out until after the video.

    I’m surprised to see that there was even just the slightest amount of recoil…..on the plus side… looks like you have found an extremely effective load for suppression….. ;-}

    Blue dot? Leverevolution? RETUMBO? Why on earth would you use such slow powders for this experiment?

    Get some Bullseye, Clays, Red Dot or Titewad in those cases.

      You don’t know what will happen until you try it. We only had 3 heads, and trying to push them too hard could have wasted all our effort if they would have shattered when shot.

        I was actually referring to the other video, not you guys. I think you guys did a better job and chose a better powder 🙂

    I’d think you might want to use one of the powders that Hodgdon supports in” reduced recoil” loads (meaning only half a case-load of powder & still safely burn to completion):

    Like Christian says below, of the powders in this list, Clays is probably the best option in a pistol…
