Custom Aluminum .70-caliber Rifled Slugs (Video)

Let’s say you’re a guy who love to shoot things. So you shoot weird and experimental stuff. There are also people who make things, but instead of shooting their goodies themselves, they send the things to YOU so you can shoot them!

Lucky dog.

Anyhow, that’s what’s up with this Youtuber (TAOFLEDERMAUS). And this time, he’s shooting some aluminum bullets through a 12 gauge smoothbore shotgun. A machinist made these pointed, boat-tail .70-cal bullets and milled deep rifling grooves right into the bullets themselves.

Each of the slugs weighs about 20 grams, or 7/10 of an ounce, and are made of 6061 aluminum–and they’re two inches long.

They were made in three different rates of twist: 1:28, 1:20, and 1:10. In case you don’t know, twist rate is the distance, in inches, which the projectile must travel while rotating at the rate dictated by the rifling. So in this case, 1:10 is the fastest because the bullet will spin once in just 10 inches of forward travel.

Each bullet has 6 rifled grooves.

First up was the 1:20 slug.

Shot 2 was the 1:28 bullet.

Shot 3 was the 1:10 bullet, but they changed another factor by firing it with a high-brass (more powerful) shotgun shell.

Shot 4 was another 1:20 slug (same twist rate as shot 1), using the same low-brass shell as shots 1 and 2.

Pretty awesome impacts on the targets, but did they fly straight and true? Check out the video to find out.
