I am finding it hard to find load data and formulas. Does anyone know where I can find good websites for these. Currently I am looking for a load for my .40 I have 155 gn berrys plated bullets. I am also getting ready to start some .45 LRN hard cast. Is there one powder that i can use for both? These are going to be used for target shooting and would like mild to medium loads nothing to hot or fast. I currently have Blue Dot powder only. Not opposed to getting something else just that is what I have.
