What is the difference between copper and brass?
You may have noticed on our website that we have both brass and copper offerings. There are small differences that set the two apart and sometimes make one a better option.
Difference #1: One is lead free, one is not.
• Copper is 100% Lead Free, approved for use in all Lead Free Areas
• Brass naturally contains 2% lead. To be considered lead free, the material must have less than 1% lead content.
Difference #2: Copper is soft and brass us more brittle. 
• When it comes to our controlled fracture design for our expanding bullets, those 2 things make a difference. The blades on the brass bullets snap off after penetration. The petals on the copper bullets peel back, and then break off.
Difference #3: Impact on Barrel
• Although copper is soft, our bullets do not foul your barrel as you would expect. Our patented SeaTite Band traps the gasses behind the bullet to slow the fouling process significantly. In addition, the bearing surface on our bullet is already short which also greatly reduces fouling.
• Although brass is harder than copper, it will not ruin your barrel. Brass has a cleaning effect on barrels (although it does not replace cleaning altogether). Our brass bullets also have a reduced bearing surface in order to cut down on pressure.
Difference #4: Application
• Brass is excellent for short range, high trauma hunting (like our Safari and Raptor Lines)
• Copper, typically, has a higher BC for those longer range shots (Hunting and Target shooting!)
