I had the same question concerning the 120gr 7mm and 130gr 30cal bullets so I sent a message to Barnes and this was their reply.
We test primarily in water and in some cases we have found that tissue may actually cause the bullets to expand at lower impact velocities. Especially with regard to the TTSX bullet design. The .308 cal 130gr TSX is tested at 1800fps and the TTSX version at 2000fps. The 7mm 120gr TSX is tested at 1800fps and the TTSX at 2000fps.
