Thanks for your help
Besides the 7mm STW, the 7 mag is my all time favorite round. Very SHOOTABLE, accurate, easy to get to shoot, and they hammer game. Like Dick said, " H1000" is a great " go to" powder. It really works well with heavy bullets, and 26 inch barrels. My 700P loves that powder, and 168 Bergers .
I have a 700 LSS that loves 67.5-h 4831sc, and a 140 TSX. I use a win. WLR standard primer. In a 7 mag, you do not have to use a mag primer. IMHO.
As far as what is the max load, your gun will be the deciding factor on that. It will tell you when enough is enough.
I have never used H 4350, but have heard good things about it from others. The field is full of options as far as powders, bullets, brass, and bullets. The seven is a exceptional cartridge, and shoots amazingly accurate. And you won't burn out your barrel, before you find your load, but you must experiment.
