JSB Pellets Picture Required

Walk away. Order online. 
Think about the nose cone of airplanes. It's the first thing to hit the air the plane is passing through. There's no protruding seams because it would create drag. On a plane it might not be a major control issue. But, on an 18gr pellet it could lead to terrible accuracy, spiraling, and missed shots. Those are my thoughts. 
I'd post a pic for you but, I'm at work. Sorry
