John,I have never loaded the combination you are asking about but have loaded a lot of Longshot in 28ga. and 20ga.My guess is that it is too slow for light loads in the 12ga.Longshot likes pressure and speed to burn right at all.There are many powders that will work well for what you desire.Hope to see you in a few weeks at the Spring Shoot in Carlisle Pa. on March 20.Charlie.
