Gus,

if you can get Norma powders, you will find some data at www.norma.cc Norma still makes the brass.

These loads were published in no. 5 of the Swedish �Vapentidningen� in �94.

Barnes X 250 grains Vihtavuori N-140 53 grains 700 m/s
Barnes X 250 grains Norma 202 51 grains 655 m/S

Barnes X 270 grains Vihtavuori N-140 51 grains 672 m/s
Barnes X 270 grains Norma 202 49 grains 635 m/s

Lapua Mega 285 grains Vihtavuori N-140 49,5 grains 640 m/s
Lapua Mega 285 grains Norma 202 48 grains 610 m/s

Back off a bit and use them with care!

The author of the article tried Norma 201, 202 and 204. 201 and 202 seemed too fast and 204 too slow. Maybe the new 203-B would work and then give results similar to N-140 ??
In the 9.3x62 it�s supposed to give some 20-25 m/s more than 202.

Good luck!!
