That is 4 gr. above max in the hornady manual. Hornady saya 70.3 @ 2700fps so I would guess that that should be arround 2900-3000fps.

Quick load gives an estimated 2865 fps out of a 26" barrel. They also predict a peak pressure of 50150 psi. This is not a max load according to Quick Load.

Doc, That load is a little over in the Hodgdon book, 73 being max, I'd say your velocity is about 3025, they're using a Speer bullet, Win. case and Win. LR primer. 24" bbl. Jay
