Ready Gunner+3Firearms Depot+3Buds Gun Shop+3 What that means on target: Carefully chosen 77gr TMK bullet for its weight, ballistic coefficient, and aerodynamic profile Consistent powder charges and new brass cases for tight velocity spreads Designed to achieve sub-MOA groups in quality rifles when the shooter does their part Whether you’re shooting paper at 100 yards or ringing steel past 600, this load is engineered to remove ammo as a variable so you can focus on fundamentals and wind calls. 77gr Tipped MatchKing – High BC, Low Drag, Serious Precision At the heart of this load is the Sierra 77-grain Tipped MatchKing (TMK), a projectile known for its streamlined shape, polymer tip, and excellent ballistic coefficient. Impact Guns+3Saint Barbs Bullets+32Ammunition+3 Advantages of the 77gr TMK: Polymer tip sharpens the meplat and improves aerodynamics High BC helps minimize wind drift and maintain velocity at distance Designed as a match/precision bullet, not a hunting bullet, focusing on accuracy and consistency This makes the Atomic 00459 load extremely well suited for SPR/DMR-style AR-15s, bolt-action .223 precision rifles, and any platform set up for long-range .223/5.56 work. 2600 FPS & 1155 ft-lbs – Optimized .223 Long-Range Performance Factory specs list this load at roughly 2600 feet per second with 1155 foot-pounds of energy at the muzzle. 2Ammunition In practical terms, that gives you: A flat-shooting trajectory for .223 Rem with a heavy-for-caliber bullet Enough energy and velocity to stay stable and supersonic well past typical mid-range distances (depending on barrel length and conditions) A recoil impulse that remains mild and manageable, ideal for fast follow-up shots and extended training sessions This is the sweet spot for shooters who want serious precision without getting beat up by recoil. Flash-Suppressed Powder – Cleaner Sight Picture & Better Low-Light Shooting Atomic uses flash-suppressed powder in this load, which helps reduce the visible muzzle flash—especially important for shorter barrels and low-light environments.
