My Fierce Fury just arrived and I am itching to start working up some loads. I plan to start with a 162gr ELD-X. There are 5 powders that can reach 2900-3000 fps via Hornady's reloading manual. I currently have IMR-4831 and RL-22. The other three powders are Magpro, H1000, and RL-25. Are there any advantages to the H1000 versus RL-22 / IMR 4831 for example?
I've found that Reloder 23 and 26 run close to Reloder 22 and 25 respectively and are more temp stable. I've run a lot of ladder/speed tests against H4831SC, Imr7828sc, Retumbo. Reloder will always outrun these powders in my 7RM.
Since I have used Nosler brass, I cannot push these loads to find and use max pressure as it opens primer pockets in just a few reloads. Therefore, some results other guys have may be different.
So basically I am not scalding hot on my reloads, but just staying a few percent less powder than most do. I settle for hunting accuracy rather than that last node I know I'm leaving on the table. Reloder gives me more speed without having to go over the max data of the other brands.
