For varmint hunters running bolt guns chambered in 6mm Creedmoor varmint ammo, the Nosler Varmageddon 70-grain polymer tip load brings the speed and energy necessary to anchor ground squirrels, prairie dogs, and coyotes at distances where traditional .223 Remington runs out of steam. The 6mm Creedmoor cartridge is a short-action centerfire round based on the .30 TC case, necked down to accept .243-caliber bullets — it combines the ballistic efficiency of high-BC projectiles with moderate recoil, making it equally viable for precision target work and field varmint control. This 20-round factory load from Nosler pushes a 70-grain Varmageddon polymer tip bullet at 3550 feet per second, generating 1959 foot-pounds of muzzle energy and delivering explosive fragmentation on contact with soft tissue.
Built for the Box
Each case is checked for correct length, necks are sized and chamfered, and flash holes are verified for alignment before powder charging. Nosler meters each charge by weight rather than volume, ensuring velocity consistency lot to lot. The 70-grain Varmageddon bullet features a thin polymer tip that initiates rapid expansion at impact velocities above 2200 fps, a flat base for ease of manufacture and consistent seating depth, and a lead-alloy core designed to fragment rather than penetrate — minimizing pelt damage on fur-bearing predators while ensuring immediate incapacitation on burrowing rodents. With a G1 ballistic coefficient of 0.334 and a sectional density of 0.169, this projectile sheds velocity faster than heavier 6mm offerings but retains enough downrange energy for clean kills inside 450 yards when zeroed at 200.

This load sits in the lightweight end of the 6mm Creedmoor spectrum — most factory offerings cluster between 90 and 108 grains for long-range target work or big-game hunting. The 70-grain Varmageddon sacrifices downrange retention for maximum velocity and explosive terminal effect, making it purpose-built for 6mm Creedmoor ammo applications where the target is small, the range is known, and overpenetration is a liability rather than an asset.
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.
