:grin: I seem to remenber reading that the twist rate for the m96 6.5 x 55 mauser was  8 7/8". now i've read other post stating  it was 1 in 7". I am thinking of tring cast bullets and need to know.
Thanks

The twist is officially in metric measurement but is generally conceded to be a 1-7.5" twist.  With cast bullets of 120 to 160 gr your best accuracy (1 to 2 MOA at 100 yards) is going to be around 1400-1500 fps. Reasonable accuracy (3-4 MOA at 100 yards) can be obtained upwards of 1700 fps but regardless of how hard you cast the bullets, what lube you use or what powder you use the deciding factor is RPMs and the 1-7.5" twist revs the bullets up pretty fast.

All my literature shows the twist rate of the 1896, whether carbine, short or long rifle at 1 in 7.5".  Mikey.

:grin:
I was ready to give up on the m96, but might not a 150/160 grainer hard cast gc fly well at this twist and at moderate speeds? :roll:
