I shot 100gr. of Black Mag'3 under Harvester sabots with 300gr. bullets and chronographed three shot average of 2004fps at 7000ft. altitude 60degrees using Winchester 209 primers in my stainless .50Omega. The same load with Winchester small rifle primers in the .25ACP conversion registered 1940fps. I actually lowered my charge to 90gr. for hunting and managed to get my cow elk with that load. Shot completely through the chest cavity with no major bone contact. SST bullet.
