7mm mag load question.
I have conflicting data on a 7mm mag load. Hornady 154gr sst on top of 65gr h4831sc. My book says 59 to 66 grains. Oal is 3.29 in book but the cannelure requires them to be seated at 3.225. What's your book say. I searched the net and i found folks using that same load and getting 3/8" groups.
