Hornady lead pistol bullets are pre-lubricated and cold-swaged for total uniformity and balance. Our exclusive knurling system retains lubricant over the entire bearing surface to reduce leading in your barrel. For cowboy shooters, authenticity is a strict requirement. That&';s why we build our Cowboy bullets to SASS (Single Action Shooting Society) specifications while holding them to the same stringent production standards as all our products.
