Powder for both 223 and 300 whisper?

[drgrenthum]

Currently i am using h335 for loading 62g pills for my AR. I ordered a 300 whisper/fireball upper and i would like to shoot 140-175g pills supersonic. Since i havent found any receipes for h335 for the 300 whisper can anyone recommend one or a powder that i can use to reload both 223 and 300 whisper. Just trying to keep types of powder to a minimum around here.

I never plan to go subsonic so that is not an issue in powder choice.

Thanks for the help.

Nor will you find more then maybe one or two with very heavy sub-sonic bullets.

The .300 Whisper uses what amounts to slow pistol powders in supersonic & subsonic loads with most bullet weights.

But there is no good powder for use in both the .223 & .300 Whisper.
