I know that most of the Alliant powders have relatively high flame temperatures.  I am wondering if Universal, which I believe has less nitroglycerin than Unique burns cooler?

Mark,

In the testing we've done here, it does seem that Universal Clays burns at a lower flame temp than Unique.  Of course we don't have equipment to quantitatively measure this here, but in our experience and test bear out your postulation.

Interesting too, I believe AA #5 to have an even lower flame temp than either Univeral Clays or Unique.   A powder well worth it's place on the loading bench for mid range bullet weights in a broad spectrum of applications.

God Bless,

Marshall

Hi Marshall,
Flame and "face slapping" has increased since I had my RSRH ported. I also think it is more noticeable because of the scope requiring my eye and head being higher to the bore-line and more exposed. Unique is a little worse than Universal.
