One thing to keep in mind with the 300 mag Federal Partition loads. They are loaded with Protected Point Partition bullets, not standard Partitions. The Protected Point load does not retain the flat bullet flight path, energy or velocity that a standard Partition bullet does. I have found accuracy to be extremely bad with the PP's, almost as bad as TBBC. The standard Partition is my favorite but you will not find any ammo manufacturer that uses it because of the length of the 300 case. I have no first hand knowledge but have heard many good things about Remington's Safari Grade A Frame loads. Good luck !
