There are no unsuitable powders for a 3" mag. It just depends on what you are trying to achieve. You will ALWAYS get the max vel from the slowest powders, BUT, you will pay for that with a larger flash & blast. For plinkers, anything from BE thru HS6 will work fine. TOugh to beat Unique or WSF as an all around choice for a 44mag snub.
