Barnes tsx given to me??

[Rupe]

I was given a box of 168gr Barnes tsx bullets and I was hoping someone could tell me how rhey liked or disliked them. What is a good load for them out of my Striker .308win
I have 3031, H4895, IMR4895, and Varget. 15" barrel and a brake. Any help I would be grateful for. Will be shooting out to 400 yards.
Thanks Rupe
