The Barnes M/LE TAC-XP .40 S&W/10mm 125gr pistol bullet (brand part no. 30500) is a .400-inch, flat-base hollow point machined from 100% copper with no lead core, giving handloaders a lead-free option for personal defense and duty-grade ammunition in either .40 S&W or 10mm Auto. Barnes built the TAC-XP line to retain its original weight and track straight after passing through mid-level barriers like windshield glass, plywood, and metal car doors, a real-world consideration for anyone loading rounds meant to perform beyond a bare ballistic gel test. It ships 40 to a box.
