This dart is almost a perfect fit in 3/4" Type L copper tubing.

This photo shows the brass ring, but it was cut off prior to shooting.

The weight is 212 gr with a 10d nail.

Chronograph result was 656 fps at 600 psi.

A hole in one! The nail went through the plywood behind this board.

The blowout at the rear. I stuck the hull into the hole for the photo. It actually bounced away.

What happened to the hull on impact.

Do you just stick the nail through the primer hole? Or did you use some glue or epoxy or something to hold the nail in place?

Nice work as always boyntonstu i really like your work in the diy darts. I never knew shotshells fit snugly into any size of commercially available copper pipe, now I have an idea.
Yeah, it's that important.

I used hot glue to attach the 10d nail to the hull.

A glass marble can be used instead of a nail makes a 160 gr round nosed projectile.

I shot one at 712 fps today for 180 FPE.

A BIG find today!

I discovered that by using a heat gun on the steel end cap of the hull just enough to make the plastic begin to flow, I could twist the steel off with a pair of pliers.

No more metal grinding for me!

Just 30 seconds and you have an almost perfect tail in your hands.

Use a bench grinder for another 10 seconds to trim away the plastic bulge.

I keep a 2" length of barrel tubing next to the grinder as my fit tester.

Shotgun shells are nice because you can put almost any kind of payload into it. And then when the shell is all torn up weld a nail to a few washers hot glue it in and you have a dart. I've only used them as lawn darts though.
