I had Robert Kleinguenther do some work for me. When he found out I was a handloader he wanted me to do some loading for him. His load for the 300 wby is 84.9 grains of 7828 with a Federal 215. He also used 180 grain Hornady flat base bullets. I always thought he should know because of his working for Weatherby.
This load was always very accurate in every rifle I tried it in. Hasbeen
