The Hornady MonoFlex .308 caliber 140 grain bullets deliver exceptional expansion and weight retention for reliable terminal performance. These solid copper bullets feature Hornady's patented Flex Tip technology, ensuring consistent expansion across a wide velocity range while maintaining deep penetration.
What Makes This Different
Unlike traditional lead-core bullets, the MonoFlex construction uses 100% copper alloy with a patented elastomer tip that initiates controlled expansion upon impact. This design eliminates lead fragmentation while delivering up to 95% weight retention. The streamlined profile and boat-tail base provide superior ballistic coefficients compared to conventional soft-point bullets.
Key Features
- Patented Flex Tip technology ensures reliable expansion at velocities from 1,600 to 3,000 fps
- Solid copper construction provides 95% weight retention and deep penetration
- 140 grain weight optimized for .30-06, .308 Winchester, and similar cartridges
- .308 inch diameter with boat-tail design for improved ballistic coefficient
- Lead-free construction meets California and other non-toxic ammunition requirements
- Consistent jacket thickness maintains accuracy and terminal performance
- 50 bullets per box with consistent weight sorting
These bullets excel in hunting applications where deep penetration and controlled expansion are critical. The copper construction maintains structural integrity through heavy bone while creating devastating wound channels in soft tissue. Range testing shows consistent sub-MOA accuracy in quality rifle barrels, making them suitable for precision hunting at extended ranges. The lead-free design makes them legal for hunting in areas with non-toxic ammunition requirements.
