Remington Bullets 9mm (355 Diameter) 147 Grain Jacketed Hollow Point available now (2010) at Midwayusa. I had to see it to believe it. Who said only flat base bullets are accurate? I ask Remington ".Can you give some history on said bullet." There reply "Why it has the bubble shape is due to the manufacturing process." This bullet base design will keep the hot gas from getting in front of the bullets nose as it leaves the muzzle, resulting in a more accurate cartridge.
