Wieland Rolled Products NA is your first step to quality ammunition.

We take great pride in maintaining longstanding relationships with both commercial and military ammunition manufacturers who rely on us for high-quality ammunition components with a combination of material quality, technical expertise and professional service no one else can offer.


Our product portfolio includes first draw cups, bullet jackets and strip products for all commercial calibers and military calibers up to 20mm. The copper alloys we utilize for these products exhibit the excellent quality, good corrosion resistance, and appealing aesthetics demanded by military and recreational users alike. They are also noteworthy from an environmental standpoint, as our copper and copper alloys provide a sustainable resource that is environmentally benign and fully recyclable.
