Hey folks. Some info needed if you have it. Ihave been loading my 12 ga. shotgun ammo for years with a MEC Sizemaster and using HS-7 and or Win. 571 and both of these powders are going away soon, maybe the 571 is already gone. But does anyone know an easy switch to a different powder that is close to these in that I won't need to change my charge.
