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.
Thank you for the heads up, got me out of bed an hour early but it was worth it. I use RL23 for a 6.5x284 and a 300 wm, but in my opinion it is very versatile in cartridges where case capacity isn't an issue. Thanks again.
