7mm Berger Load Help

[mountainmac1]

I am putting a new load together and need some help. The load I am putting together is for a 7mm Remington Mag with a Berger 180 grain VLD bullet. I am wanting to get the maximum speed out of this and wondering what is the max amount of powder I can use safely. Please let me know of any suggestions on the brand of primers and powder that have worked well for you. Thanks

If your looking for speed stick with retumbo, rl25 or h1000. I usually start my loads at .010 off the lands with bergers if the magazine will allow.

Retumbo is a good powder in the 7mm ans is not temperture sensitive.
