I'd be very interested in the results.

I have found in making my own BRRRR! tests that the rifle temp does make a difference as well. Which is why I put 'em out with the ammo overnight before running any tests. They are inside soft cases, and left inside them until they get shot. This keeps them from frosting up inside a warm vehicle.
