The Nosler Varmageddon 6.5 Grendel varmint ammo in 90-grain polymer tip configuration is engineered for shooters who need flat trajectory and violent expansion on small-bodied targets at long range. 6.5 Grendel refers to a cartridge designed for the AR-15 platform, offering superior ballistic coefficient and downrange energy retention compared to .223 Remington while maintaining magazine compatibility. This load exits the muzzle at 2800 feet per second with 1567 foot-pounds of energy, delivering a sectional density of 0.184 — balancing velocity with enough mass for wind bucking on open-country varmints.
Performance at a Glance
Nosler builds the Varmageddon line around flat base bullets with either hollow point or polymer tip designs, prioritizing rapid fragmentation over weight retention. The 90-grain Varmageddon polymer tip uses a thin jacket and soft lead core optimized for explosive terminal effects on prairie dogs, ground squirrels, coyotes, and other pest species. Each case is checked for correct length, necks are sized and chamfered, flash holes are verified for alignment, and powder charges are metered to tight tolerances. Boxer primers allow reloading; brass cases are non-corrosive and factory-new.

This load fits varmint hunters running bolt-action or AR-platform rifles chambered in 6.5 Grendel who need minimal pelt damage and maximum on-target effect at 200–400 yards. The flat base design sacrifices some ballistic coefficient compared to boat-tail projectiles but simplifies manufacturing and maintains acceptable trajectory for typical varmint engagement distances.

Safe Handling & Compliance
Federal law requires purchasers to be at least 18 years old for rifle and shotgun ammunition, and at least 21 for handgun ammunition. Ammunition cannot be shipped to certain states, counties, and cities — review our ammunition shipping restrictions before ordering. Store ammunition in a cool, dry location away from heat sources and out of reach of unauthorized users.
- Observe the four rules of firearm safety at all times — treat every firearm as loaded, keep muzzle pointed in a safe direction, finger off trigger until ready to fire, and be certain of your target and what lies beyond it.
- Verify your firearm is chambered for 6.5 Grendel before loading — consult your owner’s manual or a qualified gunsmith if uncertain.
- This ammunition contains lead, a chemical known to the State of California to cause cancer and reproductive harm — wash hands after handling and avoid inhalation of primer residue or bullet fragments.
