What to know about .243 Winchester varmint ammo
Lightweight 55–75gr polymer-tipped bullets at 3,600+ fps make the .243 Win a long-range option for prairie dogs, coyotes, and groundhogs. These bullets fragment on impact, which reduces ricochet risk in pest control. The .243 Win reaches out farther than any rimfire varmint cartridge and carries more energy than .223 Remington at distance. The tradeoff is cost — roughly 3–4x what you'd pay for .223 Rem varmint loads.
