Certainly a lot of responses here that don't help the OP one bit. He just wants to know which AA powder to use for his .33 Win levergun. HE DOESN'T HAVE ALL THE POWDERS folks are recommending.
Hopefully TCRken has a chronograph. Load up using the 2520 and see what it takes to get to 2,100 fps. If things looks safe there, cautiously approach 2,200 fps….
Since the OP hasn’t been back to the forum since January, he won’t see your post nor any others since then. As is so often the case, reviving a zombie thread does the OP no good service.
