I use AA7 with MG 158 gr. JHP bullets. I also use Mag primers because I had plenty of them when I worked up the load. Mag primers are not needed with AA7 powder. Mag primers do raise pressure levels.
I also have the Speer book but found the data listed for max. and min. loads to be better with Accurate's listing. My load is quite accurate and works for me. I haven't check the speed of the bullet. I just want an accurate clean burning load. When you have conflicting data use the lower data and work up.
