OverkillWhat 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.

OverkillWhat velocity do you get with the Norma 204...?

500grainsI use Re 15 and IMR 4350.

Ulrik HentzerIn 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.

OverkillUlrik Hentzer,
Do you think it is possible to get 2700 f/s with a woodleigh 750 grain soft nose bullet and with what powder...?

OverkillUlrik 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...?

OverkillUlrik Hentzer,
What does Hannibal rifle weight in kg...?
Do you have any muzzle brake on it...?
And how is the recoil whit 750 grains bullets in 2700 f/s...?

Ulrik HentzerOverkill !
1)- 6,2 kg
2)- No muzzle brake ( 3 mercury recoil reducers )
3)- VERY heavy
