yes Ogz, you're right about the whole in the center where it is traditionally been for better burn when the pellets came out. If you look at the new Knight with the Power Stem, it puts the flame at the top of the powder charge and makes it burn backwards making a faster and more thorough burn they say. I don't see how this innovation from Hornady would make it fly better and hit harder. Its just an attachment of the sabot to the powder. Thats all itsn't it guys? If I was concerned about making a harder hitting shot then I would use the pellets with the hole or even use loose Triple Seven with the 209 primer. I already shoot Winchester and Hornady in my front stuffer and love them but dont see these going in my gun. Interesting idea but just seems like its only for convience and speed for the second shot like the name says. Maybe for a second shot I would see them being used but not when I have plenty of time for my custom first and hopefully only shot. Interesting concept though. Maybe you're right Shredder.....plastic casing next with a built in primer? Hahaha
