Reloading ammo for TRG 42 in 338

[Piast]

I am a beginner reloader.

I have TRG 42 in 338 Lapua.

I would like to reload my ammo using Barness TTSX in 225 and 265 grains. I would also like to use VihtaVuori 170 powder.

Does anybody have any experience with this setup?

I cant speek for the TRG but do have a Timber Wolf. I would start of with the min in the book and work your way up and watch for prssure signs. What works in mine may not work in yours. Good luck and have fun.
