I fired LEGO heads from a 40 S&W

[RandallOfLegend]

I originally posted this on reddit, and a couple of pieces are in the reloading section of the forums. I figured this might have some interest across the board.

Part 1

Part 2

YouTube Video Showing a 40 S&W 180 grain vs LEGO, 40 S&W was fired first


Background:
40 S&W fires a 0.401" (10.2 mm) projectile. LEGO minifigure heads are exactly 0.401". A photo of this made rounds of reddit a while back. So I put it to the test.

Answers to FAQ.
1.) Primer Only (Winchester Small Pistol)
2.) FMJ loaded to 1.050" COAL
3.) HP loaded to 1.028" COAL
4.) Chronographing was difficult, but it came out to around 450 fps. Which at the weight of a LEGO head, is the high end velocity of an airsoft rifle.
5.) No plastic in the barrel!

I wonder what one grain of red dot would do for velocity.

This is some grade a weekend gunnit shit.

You heard it here first, this will get someone killed with an ammo mix up. lol

Plastic bullets in plastic guns! Some covert government agency somewhere is writing up the regulation that'll ban LEGO's next week. See youse guys at Toys-R-Us tonight. Let the hoarding begin.

LOL at the rifling marks on their heads.

Hey... I know that range.

Hey... I know that range.

There's still 10 lego heads somewhere on the range. They were hard to find with all the shredded plastic.

Ok, I need to do this with my 10mm now.

But I don't want to waste my good legos.

I need to buy a martyr.

I wonder if large pistol primers will give it some increased velocity.

My thoughts exactly.

LPMP maybe? :O

Just don't bring your sidearm into that commie store!

Did he fire 6 LEGO heads or only 5? Well to tell you the truth in all this excitement I kinda lost track myself. But being this is a .40 L, the first LEGO handgun in the world and would blow your head clean off, you've gotta ask yourself one question: "Do I feel blocky?" Well, do ya, punk?

My kids will either get a kick out of this or be appalled.

450fps. That's enough to piss off the cat that's been using my wife's flowerbed for a kitty litter box!!
