I am looking for a little help coming up with a starting powder charge for 168 gr barns tsx using RL22,RL25 can anybody help me.I have some of these powders left and I would like to use it.If you used these powders were they accurate?
Any help would be great thanks.

I have a fussy 300 ultra light. It does like the 150 tsx at about 3475fps but only shot the 168 mediocre.
It would be my advice to start with your favorite 180 max load and work up a grain..maybe 2 with the 168.
Here are some of barnes latest loads:

Bullet Style: TSX BT Primer: Federal GM215M B.C. 0.404

Case: R-P Twist Rate: 1:10"
