I'm looking to load up my 30-378 using the Berger 230 grain OTMs and H50BMG. I've been unable to find data on Berger's or Hodgdon's websites for this combination. Can someone please help me with some starting data or accuracy node / max load data (and the setup it was for) if you have it? I currently have both CCI 250 & Fed # 215 Large Magnum primers (side question - are these what everyone refers to as the Fed 215 or 215M's?). I have a fairly new 8lb jug of H50BMG that I would prefer to use, but I also have a little H1000 to try out if there is reason to believe it will perform significantly better. Rifle Specs: 1-10" twist, 26", ~3.845" max oal (mag restriction), chambered in factory 30-378 WBY.
