I recently cast up about 500 .44, 200gr slugs, Lee 6 cavity, with a roundnose, flat point, with a lube groove. I have new Starline brass, will be shooting it out of a Ruger 5.5" Bisley Blackhawk, that I did a action/trigger job on. I am thinking Unique will be one of my powders, anyone shoot the bullet or a similar one. All replies appreciated.
