Quote: The Hornady monos are made from guilding metal, same as bullet jackets. Harder than copper. The Barnes have the bands, but the bands are groove dia. The shank is supposed to be under bore dia.
Daryl I do not know about Barnes solids but the rest of their bullets are not bore riders. The shank is grove diameter with groves cut into the shank. The Hydros shank is grove diameter with, in effect, raised driving bands. If you look at a Barnes you will see the ogive turns into the shank, grove diameter with the groves machined into them.
