Rocky has it exactly right. The old Speer #9 manual recommended 7.5 grains Unique for .44 Mag. with a caution that patterns, such as they are, expand if loaded hotter. Of course I had to see for myself, more powder, less powder. The 7.5 grains turned out to be just about ideal.
Right on the crimping part too, except I used glue that was pretty much the same as model airplane glue. And I got about the same on pattern growth. Did manage to knock dust off of clay birds, standing right behind the trap. Maybe an Impossible Shot guy can get a shot off before the range gets too great to break one but I can't. Now that was a hoot!
