I'm not a big fan of Hornady BTSPs, that being the only one I've cared much for in a hunting bullet. Next up, they'll probably drop the 139 SP in 7mm and the 129 in 6.5 since those are the two other Interlocks that see more use in my rifles.
The 6.5 mm 129 gr Interlock is one of my favourites too, accurate in any 6.5 mm gun that I have ever tried and works well on game too. About to try some in the new 260 and expect good things.
