A quick review - I ordered some of these - 23/4" , 11/8 oz slug rounds just to try 'em out. "SCORE" is absolutely correct! I took 2 boxes of them out today & put them out of my deer barrel (fully rifled - but you can use these things in smooth-bore too...) . These things are killer accurate, literally. At 100 meters, I was hitting consistent 11/2 - 2" groups, even with a swirling 15 kph wind. I have never found such fast and consistently accurate slugs at this kind of price, ever. Get some. Seriously.
