I have about six pounds of H1000 for my 7mm Rem mag, I have a 270 I have not shot in forever a 28 Nosler that uses RL33 mainly and 6.5 Creedmoor that I am developing loads for with 140gr EOL, using H4350 and I have three pounds of RL16 to try. To be honest, I have not looked to see what it is best suited for, I just hear others on here mention how they like it and how hard it is to find.
