Like Bruce, I bought some real bargain powders many years ago that I am still shooting with no problems whatsoever. These include: H4831, Norma 205 (Out of production for 30+ years) Norma 203, H4895, Win 748, H205, H570, plus a couple of others with numbers that wouldn't mean anything to most. FWIW, I paid 75 cents per pound for the H4831. The only powders that I have had go "bad" was a couple of pounds of IMR 3031 that were about 7-8 years old, and when I opened them, they were full of rust-colored "dust", a sure sign of deterioration. I am just using up the last of a big container of H4895 that I bought in 1969. worked great all through the years, still does, but I am going to hate it when the last 2 or so lbs are gone, it's been fun!!!
