Two questions:
1. Although I haven't chronographed them, Wby factory loads print higher on the target at 200 yards than does the same bullet handloaded by me with the maximum H4831 load in the Sierra or Hornady handbook. Is there any reason one shouldn't load the .300 Wby to higher pressures in order to duplicate factory velocity? After all, there is all that hype about the long freebore, the strength of the MkV action, etc.
2. Back in the early 1960s, Weatherby used to publish load data for IMR4350, since apparently H4831 was not yet available. I notice that this data is considerably hotter than maximum loads the handbooks publish now. Why?
