CCI remains the undisputed leader in rimfire ammunition, and it has two new loads for 2018. The Mini-Mag 40-grain Segmented Hollow Point features a bullet engineered to split into three equal-size parts on impact, creating three distinct wound channels that quickly take down small game and varmints. SRP: $9.95, box of 50. If devastating varmints or drilling targets at long range with a rimfire makes you grin, CCI's new VNT .17 HMR load features a Speer bullet that should turn that grin into a mile-wide smile. It has an extremely thin jacket and a polymer tip that team up to offer flat trajectories, long-range accuracy, and explosive terminal performance. SRP: $17.95, box of 50. (cci-ammunition.com)
