I was looking at some load data, trying to determine which would be the most ideal for my purpose.
In this case, I'm going after the quietest 300 blackout round that I can make. Because while commercial offerings are alright I guess, there is probably always room for improvement by paying attention to the little details.
And in as much, I am on the hunt for the best powder choice for that. I have looked at many different brands and different powders in their lineup the last couple of days that have published data and I keep coming back to hogdon.
Below are snips of their load data for 208 gr.
I ordered a pound of H4198 because it looks like it has the least pressure of the bunch. I also understand that CUP and PSI are not the same thing.
Nevertheless, less pressure should (I HOPE) be easier for the suppressor to make it more quiet if comparing apples and extend brass life. Further, I will likely downgrade the charge to about 10.8 - 11.0 gr because I prefer to be closer to ~1025 fps due to my elevation and to give a little wiggle room in hot weather and I think 10.8 will probably get me there.
If there is anyone here who can convert CUP to PSI, I would be interested in hearing roughly what the PSI of these would be.
