    Does anyone know if there is a measured g7 coefficent for the 123 gn hornady amax?

    I have been searching for it as well. List is .510. From some data at snipershide, it looks like it is more in the .495 range.

    I am looking forward to trying to research some of this stuff this spring. I had a pair of grendels at the range yesterday. It was fun. I am always pursuing that accurate, fast load.

        I called Hornady and asked them(several months ago). They told me there was no G7. However I ran my range results thru JBM and I came up with exactly half the .510 figure. .255 was spot on for my data.
