ADI .223 Remington 55gr SBK BT Ammunition - 20 Rounds (200 Round Case Available)

ADI .223 Remington 55gr SBK BT ammunition delivers reliable performance for varmint hunting and small game work. Built on over 130 years of propellant and ammunition engineering, ADI World Class rounds are trusted by serious marksmen who demand precision and consistency. This load pairs a 55-grain Sierra BlitzKing bullet with match-grade annealed brass, offering the accuracy of a match round with terminal performance optimized for hunting.

The Sierra BlitzKing projectile uses an acetyl resin ballistic tip that promotes explosive expansion on impact while maintaining the flat-shooting characteristics you need in the field. The boat-tail design increases ballistic coefficient compared to flat-base alternatives, helping you maintain velocity and energy downrange—practical advantages whether you're shooting from a bench or making field shots at distance. The sharp, polymer tip also improves aerodynamics over traditional hollow-point designs.

Available in convenient 20-round boxes with 200-round cases for volume shooters, this ammunition suits hunters stocking up for regular range sessions or small game seasons. The combination of quality brass, proven propellant knowledge, and proven Sierra bullets makes ADI a practical choice when accuracy and terminal performance matter.

Frequently Asked Questions

What's this ammunition designed for?

ADI 55gr SBK BT is built for varmint hunting and small game work, where the Sierra BlitzKing bullet's explosive expansion performs well on lighter targets. The boat-tail and ballistic tip also support accurate shooting at longer ranges.

How does the boat-tail design help performance?

The boat-tail profile increases the ballistic coefficient, which means the bullet retains velocity and energy more effectively downrange. For .223 hunting and target work, this translates to flatter trajectory and less wind drift at distance compared to flat-base bullets of the same weight.

What's included in this purchase?

Each box contains 20 rounds of loaded ammunition. Larger 200-round cases are also available if you want to stock up for regular shooting or hunting season.

Is the brass reloadable?

This ammunition uses annealed match-grade brass, which is a quality component. Reloadability depends on your personal preferences and equipment; ADI does not specify whether this brass is intended for reloading.
