I've done quite a bit of 7/08 loading with 140 gr bullets. I have had 3 different 7/08's still have 2. Powders that worked good in all 3 with the 140 gr class bullets were WW760--H100V--StaBall 6.5 and H 380. Accuracy was good and velocity, depending on the rifle, was between 2950 and 3000 ft/sec JME
