Hard Cast Lead Bullets for Cowboy Action and other shooting sports

Cowboy Bullets Logo by Slash K Logo

/K (Slash-K) manufactures high-guality hard cast lead bullets for Cowboy Action and other shooting sports where a lead bullet is desired. UniqueTek has partnered with /K to bring this line of quality lead cast bullets to the market.

Our Bullet Alloy: We use a 2% Tin / 6% Antimony / 92% Lead bullet alloy for casting all bullets. We buy bullet alloy directly from a local foundry that has the knowledge, equipment and experience to manufacture bullet alloy to exacting specifications. Since our manufacturing is close to the supplier, we can keep our prices competitive.

Our Bullet Casting: Our bullets are cast using only Magma Engineering commercial quality bullet casting machines with Magma Engineering bullet molds. These casting machines are the "industry standard" and yield bullets that are true to the mold, free of voids and have a nice clean finish.

Our Bullet Size & Lube: Our bullets are sized and lubed using a Magma Lube-Sizer and lubed with ZAMBINI® Red by Rooster Laboratories. ZAMBINI® has proven itself time and again to be the most effective lube you can buy for the prevention of barrel leading. With a 220ºF melting point, it will not melt out and kill your powder. It is a hard, tough formula which bonds securely to the bullet.

Inspection: Bullets are inspected before packaging to ensure quality. Any bullets that are dented, misshaped or don't have lubricant completely around the lube groove are culled out.

The result is high-quality bullets which are accurate, shoot well in any weather or climate and pleasant to handle when loading.

Customer Feedback
"The bullets from /K have been fantastic. Barrel leading waaaaay down and accuracy has been impressive for both the 9mm and .38 spcl. Keep up the great work and thanks for making all of these items available." — Jeffrey S. – Tucson, AZ
