Sig C223Vp4020 Varmageddon 223 40G 20/10
The Sig Sauer Varmageddon 223 40-grain rifle ammunition delivers flat trajectory and explosive expansion for varmint and predator hunting. Built on Sig's commitment to consistent, reliable ammunition, this .223 Remington round is engineered specifically for the speed and terminal performance varmint hunters demand. Whether you're managing prairie dogs, coyotes, or other small to medium game, this 40-grain load offers the ballistic efficiency and accuracy needed for clean, ethical shots at distance.
The Varmageddon line balances velocity with precision, making it a natural choice for shooters who want factory ammunition tuned for varmint work rather than general-purpose plinking or defense. At 3650 feet per second, this round generates the velocity needed for effective range extension while remaining manageable in most .223 platform rifles, from AR-15s to bolt-action varmint rigs. The 40-grain projectile weight is a sweet spot for .223—light enough for flat shooting but substantial enough for reliable performance on target.
Sig ammunition is manufactured to the same exacting standards as their firearms and optics. Each round is inspected and loaded to deliver the consistency hunters and precision shooters expect. This particular offering comes in a 20-round box, making it convenient to stock up or try before committing to a larger quantity. If you're building a varmint load or looking to switch to factory ammunition that's been purpose-built for the job, Varmageddon rounds are worth serious consideration.
