[QUOTE="J E Custom, post: 397116, member: 2736"] Even though they are listed as the same, H4831sc slightly faster although not much and it may just be that it is newer or powder density is different because of grain size. The one good thing about 4831 is that it is linear in pressure when increased .5 grains at a time you can count on pressures increasing in predictable amounts. Retumbo does not share this trait.(You can up the loads with predictable pressures then all of a sudden pressures go off the charts).I have experienced this phenomenon with H4350 and retumbo plus some of the re loader powders. There are faster powders but speed is not the only thing to consider when loading for a rifle or a pistol. J E CUSTOM [/QUOTE]
