What kind of slug is this?

[scout3006]

Several years ago, I was in Italy and stayed in a relative's house in the countryside just outside Rome. I met a friend of theirs who happened to be a hunter, and liked to hunt wild boar. He then showed me his shotgun, (an over/under Beretta - there's a surprise... ) and one of his boar-loads that I've never seen anywhere else.

It was a rifled slug, but instead of a conical shape it was a hollow lead tube with the rifling on the INSIDE of the tube. It reminded me of some 12 gauge cookie-cutter. Has anyone ever seen or heard of anything like this? He said this load was accurate and deadly on wild pigs, but I've never seen anything like it anywhere else.

I saw those online last year i believe - kind of a 'prop' idea, wind imparts rotation as it passes thru the slug.

Can't remember where now ..

check this out, inside the hollow point there are little petals that look like rifling fins. My buddy uses them every year for dear hunting.

The Fins are for expansion upon impact with the target.
