I am looking for a good subsonic load for a 300G 44mag. I know 44 special will be work but I would like to have a good and reliable load for my 77/44
thanks
Manuals are the best place to search for the best powders for reduced loads. Stay away from magnum and ball powders (typically) as they are dangerous in reduced loadings. You will get delayed and erratic combustion with them if they are not close to full case level. Check your manuals before attempting this.
