Those extra 5 or 6 grains of powder could be the difference between you getting eaten by a bear or blowing your own face off with your rifle.
It’s kind funny when there are statements like this. “His load as he stated it was probably 5-6 grains above max saami pressure for the 300 WM.” Wow! Kind of apples and oranges there bud.
I’m not recommending anyone exceed limits with their loads. As stated above 26th edition Hodgdon Data Manual states 83. I very judiciously worked up to 85. A lot of other factors can be weighted. That is why I stated my procedure above. I’m not hiding this at all, I very openly and willing gave this to T/C Arms, the jury, and this forum.
H-1000 is one of the slowest burning powders around; which makes a 2 grain increase not much of a pressure rise. Hand loaders can archive more constant accuracy, and pressures over factory loads. Factory loads on a hot day in the SW US or Africa can have pressure spikes well above my loads.
My loads were within SAAMI service maximum avg. pressure limits.
You can disregard everything I say but PLEASE if anyone has this gun or knows someone with one out of morbid curiosity check the headspace or have a gun smith check the headspace. I don’t know if there is much more I can add here.
