The Nosler Varmageddon .223 Remington 55-grain Flat Base Tipped (FBT) Polymer Tip Brass 20-round box is a high-precision centerfire rifle cartridge engineered specifically for high-volume varmint control, prairie dog hunting, coyote eradication, and target precision in .223 Rem and 5.56x45mm NATO-compatible firearms. A primary friction point when shooting small-caliber varmint loads is inconsistent expansion and over-penetration at varying distances, which increases ricochet risks and reduces terminal effectiveness. Nosler resolves these performance limitations by pairing its precision-drawn reloadable brass cases with a frangible 55-grain polymer-tipped bullet, delivering flat downrange trajectories, low recoil, and immediate terminal fragmentation upon impact.
The primary technical advantage centers on the 55-grain flat base profile paired with a black polycarbonate tip, a concentric lead-alloy core, and a nose-thinned copper-alloy jacket. Featuring a 0.255 G1 ballistic coefficient, the flat base configuration increases bearing surface engagement with barrel rifling to maximize shot-to-shot stability and benchrest accuracy at standard varmint ranges. Upon target contact, the polymer tip acts as a mechanical wedge, driving backward into the thin jacket and lead core to initiate explosive fragmentation without relying on yaw, converting kinetic energy into rapid terminal disruption while eliminating pass-through concerns.
Launching its 55-grain tipped bullet at 3,100 FPS, this Varmageddon loading produces an exceptionally flat trajectory with negligible recoil, enabling rapid follow-up shots and uninterrupted sight tracking through optics. Assembled using premium reloadable Nosler brass cases, clean-burning propellants, and non-corrosive Boxer primers, it minimizes carbon buildup during high-volume shooting strings and guarantees smooth feed-ramp transition across semi-automatic AR-15/MSR platforms and bolt-action rifles chambered in .223 Remington. It is an outstanding choice for field varmint control and benchrest practice.
