The CCI Maxi-Mag TMJ .22 WMR 40gr is a 50-round box of total metal jacket rimfire ammunition (CCI part no. 23). CCI calls it a plinking powerhouse, built around a 40-grain lead bullet seamlessly encased in a copper jacket for accuracy. The loads leave the muzzle at 1,875 fps and use CCI priming and brass. If you want magnum rimfire speed for target shooting without a hollow point, this is the Maxi-Mag version CCI makes for that job.
