This review compares M855 and M855A1 5.56mm ammunition, highlighting M855A1's superior terminal ballistics and fragmentation in gel tests. However, M855A1's higher chamber pressure and hardened steel tip cause accelerated rifle wear, reducing barrel life and damaging feed ramps, making it less suitable for high-volume civilian use despite its slightly better accuracy and negligible velocity gain.
