is there anyone out there that has used this powder or knows anything about it ,, thank you ,, hope this is the corect place for this post
Google is your friend. From the picture of the label I figured the container was for a ammo manufacturer and not for retail sales. Type S341 powder in the Google search box and it will give you their site. They show a lot of different powders in what looks like 1 Lb. cans for retail sale. Problem is it looks like a South African company. RHEINMETALL DENEL MUNITION SOMCHEM POWDERS "South Africa. Rheinmetall Denel Munition specializes in the development, design and manufacture of large- and medium-caliber ammunition families and is a world leader in the field of artillery, mortar and infantry systems as well as plant engineering." "Rheinmetall Denel Munition (Pty) Ltd was established in September 2008 when Rheinmetall Waffe Munition AG acquired a majority shareholding in Denel’s ammunition manufacturing subsidiary, Denel Munitions (Pty) Ltd." "Rheinmetall Denel Munition provides propellants to manufacturers of ammunition for the sporting, hunting and the Bisley markets, as well as directly to the Reloading market."
