Sheephunter-I might be wrong but I think we're all gonna find out its the "ribs" contributing so much to accuracy. These tough bullets just didn't get into the rifling of alot of barrels before. Escpecially a bullet like the barnes which has no soft lead core to compress. So the ribs now give the "relief" needed for the bullet to properly "engrave" itself into the rifling. I think we will be seeing alot more "ribs" in the future.

FWIW, the logic and questions that led to the XXX is detailed by David Scovill in the latest Successful Hunter . I just wish I could get some of the XXX-XLCs that he showed in the pictures, one cool looking bullet. He stated that being a solid shank there was no place for the displaced (by the rifling) metal to go, thus the love/hate relationship. I kinda dig it that they resorted to 'technology' developed for lead bullets for these.

yes!!!!!!!!!!!!!!

Oh,no questions kraky,
the ribs-driving bands change how the bullet performs while in the barrel-and therefore accuracy.So maybe the TX isnt as finicky as to which barrel can shoot them.
But once out the muzzle,assuming an accurate bullet- as the Barnes X is in some barrels,the killing or wound picture I presume to be the same as the Barnes X.
