Buddy of mine bought a pound of this and then wanted to know what he should be loading it up at...see the problem I told him was neither Alliant nor Barnes have any load data for that combo...they have some for 180gr tsx in .300wsm and 165gr tsx for .300wm, but nothing for that. Now I know we can use the 180gr as an approximate and just start well back of the max loads to ensure we have a safe load but I thought if anyone was already using it I could pick your brains here. SO let me know what you got
 
In my T3 I'm finding a group shooting the 180grn IB using 68.5gn of RL19. I still have to tweak it. However I'm hoping it will transfer over to the 180 TSX. I'll be trying the 168TSX pretty soon. Max load on the Alliant Powder Site for the 165gn SP is if I recall Max. load is 73gn with a max vel. of 3135fps. I'm going to use 3gn below work up until I get 3100fps with the 168gn TSX. Hopefully I find something. Hopefully there be other who would chime in with their R19 loads for the 165/168 TSX load.
 
With the 180gr TSX they show 107% load density - could you even fit enough in with the 165gr to make it worthwhile?
