Best temp stable powder for subsonic?
Ok, hopefully this hasn't been gone over to much. I went through all the pages on here and read them looking for the best all around powder.
so I guess the question is: What is the best all around powder for a bolt action 300 whisper shooting subsonic rounds? leaning toward the 220-240gr SMK's.
looking for accuracy, safety, temp senstivity, etc
thanks a lot. Jon
