Hello I weighed 15 pieces of 6xc brass to see what they would hold for grains of water. First did I do it right. I put shot primers in the brass backwards and filled the brass to the top of the mouth so it was full flush with water. I weighed each piece empty and then full. I come with an average of 44.2 gr of water. If that is the correct way to measure that what is my next step , I have never done this before I always had starting loads for numerous powder and bullets. This caliber I have 0 data.
