Wby 30-378 Magnum

And if you want to broaden the definition of "factory ammo", Blaine Painter @ Unknown Munitions will develop & load for anything reasonable that has pre-formed brass available. He's doing my 7 Allen Mag loads for me right now, which is based on the 338 Lapua Improved case... Very happy so far.

No, IMR powder has not been imported here since the 90's.
Have been using RETUMBO and RE33, but no Alliant powder is being imported at present either. When my RE33 jug runs out that is it.
I get 3200+FPS with everything I shoot in it. It has a 32" 9" twist barrel.
The 300g Berger OTM was seeing 3280fps.
I use a CNC turned solid of 323g on steel, that gets 3215-3230fps depending on powder, but I'm not pushing them hard.
Brass lasts a long time at the pressures I'm running, over the Pressure Trace II I am only at 58,000-61,000psi.

Cheers.

whats your load using the H50bmg with a 300 gr in order to get that velocity?
