No,
I think he is talking about the flat nose solids with bands . Barnes website and ads say less pressure/more velocity are the benefits from the bands. These appear to be replacing the venerable round nosed solids. I too would be interested in feedback/experience, since I only have one box of barnes 400gr solids in .416.
Is it me, or would the flat nose open a certain pandora's box of feeding issues in bolt guns? As opposed to traditional round nosed solids.
