Is this powder any good?

[QUOTE="MagnumManiac, post: 2129562, member: 10755"] I have found clumps in all of the ADI made extreme powders, from H4895 up through to H50BMG. It poses no problems. As to the difference in specific gravity, this is normal as the solvents evaporate out of the kernels over time. 10 years is a long time for storage. My answer is to mix the 2 powders together...I do this all the time with new lots of the SAME powder. The main difference will be the pressures produced, most likely lower for the same amount of powder. Years ago, I had 2 cans of IMR 4320, one was newer by about 3 years, the older can produced velocities around 150fps slower with the same charges...I mixed the 2 together in a mixing bowl and the charges then went back up by around 100fps, with additional powder, the previous velocity was achieved safely. Anyway, take it or leave it, this is what I do, and my pressure trace shows it is safe as long as you work up your loads again. Cheers. [/QUOTE]
