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.

    Get the cheap chinese knock offs. I’m sure those are loaded with lead. Ha! Lead head legos. Great for home defense. No worries of over penetration.

    I think I prefer my hot glue bullets propelled by primers only. Much more economical. Once I work out the exact cost per bullet I figured I’d do a write up on it and submit it to TFB if they want it.

      The bullets are made of hot glue?

      • Will P.

        Yup I’ve made some of these before myself. Take your lead bullet mold, lightly oil the inside of the cavities, and fill it with a hot glue gun. Put the mold in the freezer for a little bit to harden, swing open the spur cutter, and load them into a casing by hand with just a primer. They are really neat, I was shooting them in my basement at cardboard boxes. You can collect them up and reload the “bullets” several times *Note they will go through 2 or 3 layers of cardboard so I wouldn’t recommend shooting them at your buddies or not having a good backer if you have drywall.

        • Moonman45

          are your buddies cardboard cutouts of WWE characters?

          • Will P.

            Nope but if it’ll go through a few layer of cardboard it’ll leave a nasty bruise, possibly break skin. It’ll definitely shoot your eye out kid.

          I would imagine epoxy would work even better, although the cost is quite a bit higher.

      • BattleshipGrey

        Yeah, I use a Lee .358 mold. They’re reusable too.

          Have to reply on this comment because TFB closed comments on the Klarus thread. A month ago you asked the price range on the Klarus flashlights. Both the XT11GT and XT12 run around $80.

          • BattleshipGrey

            Cool thanks.

    • Lead Kisses

      This sounds interesting

  • Tinkerer

    Someone needs to make Lego head-shaped lead-casting molds.

  • Mrninjatoes

    Nobody gives a rusty f*** about Lego bullets. Please post things that are relevant, or some girls with guns.

    • Pedenzo

      Geez dood…..what is it like….living a life devoid of humor?

      Although….girls with guns is good…..

      • Mrninjatoes

        Just show me some girls!

      • LGonDISQUS

        Love me some SHOT bunnies, but lets also try to focus on expanding firearms enthusiasm to the quickest growing market demographic, no?

    • Bill

      Yeah, because subjects like that haven’t been done to death already. How about revolvers vs autos or 9mm vs .45?

      • nonobaddog

        How about a super-slo-mo video of a 9mm bullet and a 45 cal bullet meeting in a head-on collision.
