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
