[QUOTE="gte901m, post: 1387532, member: 80740"] See attached file. The first half contains 71.4gn case capacity, and the second half is the default 74.0gn case capacity data. Your powder charge and velocity data doesn't correlate very well with the 71.4 case capacity data. Either the 71.4 measurement is not correct, or your lot of H4350 is different than the QL database. Regardless, QL predicts max pressure around 2940-2950 fps for both case capacities. Remember, QL is a prediction and not gospel. A man much wiser than me once said: "all models are wrong, some models are helpful". Considering Nosler max load data for their 168gn/H4350 is 54.0 @2,853 from a 24" tube (estimate 2,900fps with 26"), I think its safe to say you can push towards 2940-2950 before you hit the 65kpsi threshold. Keep an eye out for ejector marks on brass. [/QUOTE]
