Solo1000 is a quiet fast burning powder that will work for the 147 sub loads. It works best with 124 or heavier bullets; it is hard to get enough in the case for a 115 grain or lighter bullet.
It is also very clean burning.
The down side for me has been that the load for given velosity varies (more than most other powders) with tempurature and from lot to lot.
