I have read in numerous forums that 9 grains of Unique is a good load for the 200 grain cast bullet used in the 44 Magnum. I purchased several boxes from Missouri Bullet Company as they are listed for 44 Magnum and are cast at 18 Brinel. With 9 grains of Unique the barrel of my S&W 29 with 6" barrel leaded quite heavily.
I also purchased their 240 grain Keith bullets to load for my model 29.
Any help appreciated!
