Winchester AA Diamond Grade 20 Gauge Shotshells: First Look
This video provides a first look at the new Winchester AA Diamond Grade 20 Gauge shotshells. Jimmy Wilson from Winchester explains that the Diamond Grade line features 8% antimony alloyed with lead to create harder shot, which resists deformation for rounder projectiles and more consistent patterns. The 20 gauge version also includes copper-plated shot and a high nickel head as a visual indicator of the Diamond Grade quality. The load is intended for elite competition shooters seeking tighter patterns.
