Velocity of that load should be close to 2950 fps. Hornady manual doesn't list H-4831, and Hodgdon's basic manual that I have doesn't show that bullet, but does have a 140 gr with a "do not exceed" load of 64 gr H4831 at the 2950 velocity I mentioned. Winchester catalog has factory loads with a 140 grain bullet, either the FailSafe or the Ballistic Sivertip are listed at 3150 or 3100 fps respectvely.
