I am brand new to using surplus powders. I've read what I can about "fast" and "slow" WC 852, and nearly all of the determining factors seem to require knowing the lot number.
A friend of mine's father passed, and my friend is going through all his reloading stuff, and he has at least one full jug of WC 852. It has a label taped to it that just says to "use H-380 data" It is most likely put there by the seller, as it has the price on it, along with the weight of the jug.
Has anyone else used 852 powder that is labeled like that? I am assuming that I would be safe to start at the low end of charges listed in manuals for H-380, for my application? Is that a relatively safe assumption?
I looked at the powder, and it is a very finely grained ball powder....
thanks for any advice you can give....
