The load data I gave you, was taking in consideration that you have an 8 twist barrel ,
the load data I was referring to in that other post, that rig was sporting a 12 twist barrel,
which is 50% slower twist rate, as far as barrel rifling goes that is a world of difference,
at the same 4000FPS rate your bullet in an 8 twist barrel is spinning 360,000RPM,
oppose to 240,000 RPM with the 12 twist, respectively.
