Greetings,
There is plenty of good data around and I have not loaded the .300 Win Mag so will leave the comments on projectiles and loads to others. Belted cases can require some extra steps and I suggest you might like work with someone who loads the belted cases to take you through them. With some rifles there can be problems with resizing to give both easy chambering and decent case life. Others may wish to comment.
Regards Grandpamac.
