    i just bought a 7MM and have already played did some testing about my bullets and powders... ive used H1000, RL22 with berger and A-MAX bullets, and with my gun A-MAX is the way to go but i want to try H4831 powder but dont know where to start it if it burns hotter or not... if anyone shoots a 7MM with H4831 if you would let me know a good place to start the grains

    Assuming you are talking about the 7mm Remington Magnum and a 162 gr. Hornady A-Max, with H4831 I would start at 62 grains and work up from there watching for pressure signs. Back off to 61 grains if you are planning on jamming the bullet into the lands.
