Howdy yau'll. Im looking for anyone who has some first hand experience with this boolit in the .458 socom AR platform. I just purchased the mold and plan to cast from COWW. Im hunting primarily subsonic info for this boolit. After watching Full Lead Tacos videos, ( Awesome BTW ) I plan to PC it and size to .459. He found 4198 worked pretty well at around 22 grn / 1000 fps. Anyone have any more info?
