I do think RP may a huge mistake limiting the 260 to a 9 twist, as it sometimes causing issues with some wts., and lastly, they IMHO should have launched the gun/ammo w/120 gr Corelokts given the primary use by most hunters - Deer hunting.
The 140s initially were apparently underloaded at around 2550, vs. the 2750 advertised/spec'd.
Greg, esp. if the 130 tested was a Barnes, I can imagine being a long monometal bullet, it acts as a much heavier bullet requiring faster RPMs to shoot well.
The 120 Barnes is bad medicine IMHO in the velocity range of a 260 and 6.5x55. No doubt it will give penetration etc. like a heavier lead core 6.5mm bullet, if not more.
Can't imagine much that Fed load 'TSX' cannot take in NA, with shot placement.
