Berry s Manufacturing Hybrid Hollow Point Features The Berry s Hybrid Hollow Point bullet combines a bonded copper plating over a swaged lead core a design created by merging two separate developmental hollow point concepts into a single projectile. At .401 inch diameter and 180 grains this bullet is sized to work in both .40 SW and 10mm cartridges giving reloaders flexibility across two popular calibers. When loaded to the recommended velocity range of 975 to 1075 fps the bullet penetrates 11 to 13 inches in gelatin testing while maintaining excellent accuracy. A minimum of 98 percent weight retention reflects the bonded construction holding the jacket and core together through impact and expansion. Reloaders working toward maximum cartridge overall length should note the SAAMI maximums of 1.135 inches for .40 SW and 1.250 inches for 10mm when seating this bullet. Because the copper plating and lead core are bonded rather than simply pressed together this bullet resists the separation that can occur with lower quality hollow points under high velocity impact. Sold in a 1000 count box this bullet is intended strictly as a reloading component and is not a loaded cartridge. Handloaders looking for consistent expansion and reliable terminal performance across two common defensive and duty calibers will find this a versatile option for their reloading bench.
