This review covers Challenger 12ga mini shells, featuring both #4 buckshot and #7.5 birdshot loads. The video demonstrates their use in a Mossberg 590 SBR, highlighting the necessity of the OPSOL TX Mini-Clip adapter for reliable cycling. Performance data includes chronograph readings (birdshot ~1187 FPS, buckshot ~1167 FPS) and ballistic gel testing, showing adequate penetration for defense. The shells offer increased capacity and a 14-pellet buckshot load.
This review compares 12-gauge 00 buckshot, #4 buckshot, and 7.5 birdshot using a Mossberg 930. 00 buckshot demonstrated a tight 3-inch pattern at 6 yards and penetrated 4-5 layers of OSB. #4 buckshot spread to 5 inches and was less effective. Birdshot destroyed lighter materials but failed to penetrate dense surfaces like buckshot.
