I was given 5 pounds of Hodgon's 4831 World War 2 surplus powder. Still in good shape no degrading or corrosion evident. I plan on using this in 7MM Rem. Mag and 300 Win. Mag. I remember my father shooting up this stuff a long time ago and if I remember correctly he told me to always use reloading manuals made before the 1960's with these powders because the formula changed after the war.
My question is can I use modern reloading data, and has the powder changed much since the 1940's? All the 1 lb. cans come from the same lot number also.
Thanks,

Jeff, my neighbor and I shot up fifty pounds of surplus H-4831 that I bought from Hodgdons in the sixties. Took us a while... I used the manuals of that time for 30-06 and .270 Win. Since money was scarce I used it for 150 and 165gr with 62gr, and the 180gr with 60 gr.
Never loaded for the 7mm Mag or the 300, so all I can tell you about are the two cartridges above.
Might be a misconception about post-war formulation of H-4831 in that the powder I bought in the sixties was, indeed, WWll surplus. I understand that Hodgdon stated, when the surplus ran out, that the new formulation was the same, and that the old data could be used with the new powder. Maybe some "Seasoned Citizen" can confirm this info.. Of course, H-4831 has had several manufacturers over the years, so a phone call to Hodgdons might be in order..
