Mastercaster, First great shooting with your TTSX loads!
As per your comment that a faster twist barrel will not stabilize the LIGHTER 130 gr TTSX bullet versus the slower twist in your rifle that does.....this runs contrary to conventional wisdom. A faster twist is necessary for longer/heavier bullets or you get oblong holes in the target (caused by non-stabilized bullet) and poor groups. "Over-stabilizing" shorter/lighter bullets in fast twist barrel usually isn't a problem with copper bullets as they won't come apart like thin jacketed varmit bullets due to excessive rotational forces. That said, you probably tested accuracy and your 130 gr TTSX load wasn't accurate in the faster twist rifles....but not likely caused by the bullet not being stabilized, but due to other issues with the load/rifle combination.
