257-10-80 BBT

Ball Bearing Tip (BBT) v Hollow Point (HP)

“both will have the same deadly terminal performance retaining 95%+ of their original weight, maintaining momentum to penetrate from any angle and reliably expand from point blank range out to the 1800fps velocity threshold”.
The only difference is that BBT range of hunting bullets were designed to increase BC by 8% to 15% for maximum performance at the extreme range for each cartridge. However, BBT do not offer any advantage over the standard OEP hollow points bullet under a 350 yard hunting range.
