What powder do you guys use
What powder do you guys use in your 585 Nyati and 577 Tyrannosaur...?

And with what powder do you get the max velocity in 585 nyati and in the 577 t-rex...?

I use Norma 204 powder. So far that�s the only powder I have tested.

In my .577 Tyrannosaur I have tried N-204 and VihtaVuori N-550. Both give good velocities in the 2550-2600 f/s range but the best is the 550. 189 grs gives 2705-2715 f/s with a Barnes Monolithic solid, 750 grs.

Ulrik Hentzer,

Do you think you can get the velocity higer....?

Are you going to do any expansion tests with the woodleigh 750 grain soft nose at 2700 f/S...?
