Overview

The CMMG Resolute Mk4 in .350 Legend solves a specific legal problem for hunters in Iowa, Ohio, Michigan, Indiana, and parts of Pennsylvania, where rifle cartridges are prohibited for deer and only straight-wall cartridges are allowed. .350 Legend was engineered by Winchester in 2019 specifically to be legal in these states while offering AR-15 magazine compatibility and 250 ft-lbs more energy than .30-30 at the muzzle.

CMMG's execution on the Mk4 Resolute platform is serious hunting hardware. The 16.1-inch medium taper barrel uses a 1:16 twist for 145-180 grain hunting bullets. Energy at 200 yards runs around 900 ft-lbs, which is clean whitetail territory. The rifle uses CMMG's ambidextrous safety, enhanced trigger, and RML15 M-LOK handguard. Their Magpul MOE stock and grip round out a purpose-built hunting setup.

Recoil is noticeably softer than a bolt-action .243 or .308, which matters for longer field sessions and new hunters. CMMG includes their 5-round .350 Legend magazine (required for this cartridge, standard 5.56 mags do not work). At $1,499 it prices above budget options but delivers better fit, finish, and warranty support than unknown-brand alternatives.
