Powder Question

wfk
Not sure how to ask this question, but I'll try it this way. I'm still not getting consistent shot groups out of my 257 Roberts. I'm using Speer Grand Slam 120's behind Varget powder. My question is, could changing to a slower powder, such as IMR 4350 make any difference. I tried 4 different loadings tonight. 36.0 grains, which shot the worst, 34.0 grains, 33.0 grains, and 32.5 grains. About as good as I could get was about a 3" group at 100 yards. Not very impressive huh?

    Is there any difference between AA Solo 4100 and AA Scot 4100?

    "When in doubt, throw it out." And, if you were not in doubt you would not have asked. I have done away with a lot of older powders over the years due to the same condition. My personal opinion is that the brown powder is a sign of chemical breakdown. Spread it in you garden or on the lawn or burn it in a safe manner.

    That brown/rust color is one of the signs of deterioration. Throw it on the vegetable garden as fertilizer.

    I have powder much older than 1988 which I use from time to time; material I purchase(d) , often in shop closeouts or from estates over the years. But infrequently I encounter the dust or acrid odor in a can. *THAT* can goes to the lawn immediately. Properly stored, the stuff will last longer than I will, but when one buys older material, there's no record of it's storage conditions over an extended period.

    In my experience this is an issue of poor long term storage and more accurately, exposure to heat. As mentioned...fertilizer material! I've used and bought powder much older than that but always have checked for just such a condition
