Sig C243Vp7020 Varmageddon 243 70G 20/10
The Sig Sauer Varmageddon 243 70G is a purpose-built varmint and predator round engineered for shooters who demand accuracy and consistent terminal performance on small game and predators. This 243 Winchester load pairs a 70-grain projectile with Sig's ballistic design to deliver the velocity and energy needed for clean, ethical shots at distance. Whether you're working prairie dogs, coyotes, or foxes, this ammunition gives you the consistency and stopping power to get the job done right.
Built with Sig Sauer's attention to quality, each round is loaded to exacting standards. The 70-grain bullet weight in 243 Winchester is a proven sweet spot for varmint work—fast enough for flat trajectory and energy transfer, yet stable enough for accuracy beyond the typical 100-yard varmint engagement. This makes it equally at home in a lightweight varmint rifle or a general-purpose hunting setup where you might encounter predators.
Each box contains 20 rounds packaged in quantities of 10, making it easy to stock up for a range session or hunting trip. If you're a varmint hunter or predator control shooter, the Varmageddon line is worth trying—it's not the commodity ammunition you'll find in every bin, but rather ammunition built with the specific demands of precision varmint work in mind.
