Overkill
585 Nyati V/S 577 T-REX
Why does the 577 T-REX have the same speed whit 750 grains bullets as 585 nyati. Look at this...


577 T-REX 750 grains bullet 190 grains of powder speed 2470 f/s

585 Nyati 750 grains bullet 153 grains of powder speed 2531 f/s

There is 43 grains more powder in the 577 T-REX and the the 585 Nyati has a higer speed.

Can some on explain this to me...?

Overkill, The T.Rex. has a larger case than the Nyati and will push a 750 gr. bullet about 100 fps. faster. In the example you mentioned if the 190.0 load in the T.Rex used a powder that was too slow that would account for the lower velocity inspite of the much bigger powder charge.

190-153= 37

Yukon - 5 out of 4 people can work fractions either.

overkill

How can you be sure the data is not a lie?

500grains,

How in good conscious could you question his data? Arthur Anderson verified it.
