Hey guys, looking for input for a new reloader. Looking up 7x57 Mauser data through Nosler and they list Ramshot Hunter for loading under 175gr partitions and another. However due to availability issues, I am looking at loading a 173gr Sierra over the ramshot hunter. Would I be in the ballpark if I worked the ladder tests just right and would I be safe in doing so or should I jump into the Sierra manual and just wait for the powder to become available? Again, new to reloading and any info would be appreciated.
