New round
Brenneke has a new type of sabot slug. Its called the TOPAS and it sounds like its pretty good. If I can find some I will get a few boxes and try them out.
Anyone here use them?
TOPAS® Sabot | Brenneke - Ammunition
BRENNEKE has created the perfect combination among classic shotgun slug and sabot technology. The sub-calibre TOPAS has a cup, is barrelfriendly, quick and priced especially attractively.

Do not understand the concept of a rifled slug in a sabot.

I am not sure either.
Maybe it is so it can be shot out of a riffled barrel or a smooth-bore, but then the rifled slug would no do much in the smooth-bore.
I will say Brenneke make a heck of a slug so they must have figured it out.

Designed to be shot in a smooth bore barrel and the rifle vanes theoretically impart a spin from the air resistance as they fly and the sabot has dropped away. Kind of like when a kid holds a pinwheel out a moving car window. Just remember rifled slugs in a smooth bore and smooth slugs in a rifled barrel. Bob

+1 It's a head scratcher for me.

Maybe they've seen it begin spinning when the sabot drops off?? I am dubious.

Doubtful that with the shockwave created by the nose of the slug, sufficient air would hit the vanes to cause rotation, Bobjudy. There would be a little, possibly, but achieving a spin rate due to the effects of the air even approaching the spin rate from a rifled barrel is, frankly, impossible.
If the intent is to have people believe you can impart a stabilizing rotation with the 'rifling' on the slugs, I think it is only to have people believe it. I do not see how any significant rotational velocity can be achieved in the ranges a shotgun slug would be used.

Hard to find a review. Seems they can be fired from smooth or rifled bores. My go to for years has been Remington copper solids for rifled bores. The Federal Tru-ball has performed really well out of the smooth bores I've tried them in.

Yup, that is why I said "theoretically". They have been putting vanes on smooth bore slugs for 100 years. The consumer kind of expects it.
I think this was designed as a hybrid lower cost universal slug to be fired in any kind of shotgun barrel. Heavier and slower than a lot of saboted slugs but the sabot should prevent leading in a rifled barrel. Back when I was selling guns I had several customers spend extra on a rifled barrel and then insist on shooting the cheapest rifled slugs on the market. Didn't take many shots to scrub off enough lead in the rifling to ruin any thoughts of accuracy. At that point it is a real pain to remove all that lead fowling. One was using a rifled choke and tried to tell me the choke was defective because he shot out all the rifling. I scraped a curl of lead out of it with my knife and pointed him in the direction of the gun cleaning supplies. Bob

I have always liked Brenneke slugs, Their KO slug has been my goto slug for years.

We used Brennekes on deer years ago.Never saw one get up after a well placed Brenneke.
