    I ususally mix two powders together at a 1 to 1 ratio.

    I had a large amount of powder given to me and I didn't have equal parts and having a brainfart, I mixed them together and now I'm stuck with a difficult math problem.

    Here it is.

    I mixed 16 ounces of X with 6 ounces of Y giving me a non- 50/50 mixture. I found another 6 ounces of Y today.

    How much of the XY blend would I have to siphon off so that I can add the additional 6 ounces and end up with a 50/50 mixture of X & Y?

    Thanks in advance!! :crying:

    Why would you mix powder together do you have a death wish?

    No this isn't a joke. It's a serious math problem. If you can't solve it please keep your ridicule to yourself and get in line with me, cuz I can't either. :wavey:

    Trust me, I can do the math, I WON'T do the math for you... You're going to get yourself hurt, and I won't be a party to that.

    You can't. Buy four more oz of Y
     
  9. It probably would be easier for you to calculate had you still had all 10 fingers.

    It is physically impossible to mix two powders and have the same mix each time you measure a charge. This is why every reloading manual states

    DO NOT MIX POWDERS

    Or do you think you are too smart for the basic safety rules of reloading?

    Jeez guys, lighten up. Back in Jack's day when there were only 8 powders to choose from people would mix powders all the time.:supergrin:

    BTW,
    you'd need to siphon off 8.8 ounces (this would remove 6.4oz of X and 2.4oz of Y, leaving 9.6oz of X and 3.6oz of Y).

    The 8.8 ounces you take out would then need 4 ounces of Y added to it to be an equal mix, if at some point you want to use what you siphon off.

    Gonna have to remove approx 9 oz of the mix to be able to add 6 oz pure 2nd powder and come up with a 50/50 ratio... This would be the equivalent of adding 9.35 oz to 9.5 oz... not quite 50/50 but pretty close...

    I'm assuming your are working on spices for a beef spare rib rub - correct?

    If this is for gunpowder - you gotta ignore what I said and start all over again... my disclaimer...)

    ETA - When I said approx 9 oz - the numbers I used were 8.75 oz removed so it pretty much matches the 8.8 stated above...

    First, I don't recommend doing what you are doing. With that being said here is an Example of a possible solution. The mix you have now - 16oz. X powder + 6 oz Y powder = 22 oz total. This is almost 3 to 1 ratio but easier to do in percentages. The mix now is 72.75% X and 27.25% Y. If you take 8 oz. out that leaves you with 14 oz mix which is 10.18 oz. of X powder and 3.81 oz of Y powder. If you add your new 6 oz. of Y to the 14 oz mixture you will end up with 9.81 oz of Y and 10.18 oz. of X. This is .37 oz or 1/3 of an oz. off of a 50/50 mix.
    Again I dont recommend ever mixing powders and this is something I would not do.

    I am beginning to see the light. You know when I switch from win 231 to WSF I have to adjust the powder measure. If I blended them together I could use a weight in between and never have to adjust my load again.
    Wow I could pick up another nick name and everyone could just call me lefty.:cool:
