I have a 1903 Springfield in rem 244, and am experimenting with 75grain A-max bullets. I worked up a load form an old manual with hogdon H322. Looking back now I cant find data to support a 34 grain charge with the H322. I also noticed excessive air space in the case. The accuracy from this load .42" at one hundred yards. Does anyone have any data to support this, or did I make an accidental discovery?
