Because I don't shoot much overbore stuff, if I could only have one or two powders they would have to be IMR 4831 and H 4831 + (sc) Consistent, stable, accurate- what more can a guy want.
Occasionally a powder here or there will offer a little more velocity, but rarely have I seen a powder that offers such consistent accuracy with good velocity as the 4831 family.
I really like and use a lot of H4831. I especially liked the old surplus military stuff Hodgdon used to sell, as it was a little slower (maybe just OLD) than even the current H4831. But I find IMR 4831 to be too close to IMR 4350 (there is even some crossover between these two in the data of some manuals....) to need both. So, since I use a lot of IMR 4350 in smaller cartridges such as the 7X57mm, I have never tried IMR 4831. Just H4831 and IMR 4350.
