I use 43 grains of lever whatever with the 160 FTX.

I use 42.7 H4895 with 130 Barnes ttsx. Worked up load in Idaho this winter. Here in Portland Or ar 50 plus degrees the primers are starting to get flat. No sticky lever and VERY ACCURATE. They say H powder is extruded and not temp sensitive but she looks like the load has warmed a little.
