Well, the 30-o6 didn't care for it too much. Best group was only 1.25" and that's only 3 shots. Temps were in the upper 40's with light winds and clear skies.
The 308 on the other hand, liked it quite a bit.
Put 5 into a ragged group. The dot is 1/2"
I'll load some up and check for repeatability and run them across the magnetospeed to see how they gin along.
