Re: .300 RUM: 240gr SMK + H1000
I don't have direct experience with the 240 and the RUM.
But I ran some quickload numbers for you to use as a data point to compare against any other data you find.
80gr 50985psi 2586fps
81gr 53000psi 2615fps
82gr 55087psi 2644fps
83gr 57254psi 2672fps
84gr 59503psi 2701fps
85gr 61840psi 2729fps
86gr 64267psi 2757fps
64977psi is the max spec for the 300RUM.
The loads I have seen on the net for the 300RUM always appear to be above the max that quickload calculates. But for what it's worth, quickload agrees very closely with the Hodgdon reloading data for the 220SMK (velocity and pressure).
Hope this data helps, sorry I don't have direct info for you.
If some is good and more is better, then too much is just right.
