Need help reloading 50 alaskan with 50 bmg bullets

[shaun1921]

I just bought a SSK .50 Alaskan 20" Encore barrel that is threaded for my Gemtech Storm front 50 BMG suppressor. I now need to start hand loading ammo. I want to load 50 BMG bullets in the 650-800 grain range and have them moving around 1050 FPS to avoid the sonic boom. I plan mostly on plinking but it is legal in my state to hunt with a supperssor so I might want to try taking a deer at some point. I have not reloaded in years and do not know where to start. If anyone can share powder / bullet recommendations I would greatly appreciate it.
