Hodgdons only has load data for the 168gr TTSX, using Varget... They don't even list any Alliant powders for
ANY loads.

But ReloadersNest.com lists a verified load for the 165gr TSX, using RL-15...

One thing I like about Berger Bullets website is the chart listing for their bullets is very comprehensive, even listing "optimal barrel twist rate".
