Federal Cartridge Company and CCI have introduced a new bullet design for varmint hunting: the TNT Green.
The TNT Green ammo uses a totally lead free bullet that “couples explosive expansion with match-grade accuracy.” The ammunition uses non-toxic technology and appears to be a direct competitor for Barnes Bullets’ Varmint Grenade.
Federal and CCI state the ammunition should be on the shelves by spring 2008. Initially, the TNT Green ammo will be loaded for .222, .223, 22-250, and .22 WMR.  Bullet weights will run from 30 grains (for the 22 Magnum) to 43 grains for the centerfire cartridges.  These light weights are great for varmint hunting.  They are generally flat shooters and will dynamically expand on impact with the target.
Update: Â CCI is now offering a 16 grain TNT Green JHP load for the 17 HMR cartridge. Â This rimfire is rated at 2500 fps at the muzzle, which works out to about 222 ft-lbs of energy. Â The 17 HMR has become very popular among varmint hunters and target shooters for the great downrange accuracy these cartridges deliver. Â Fortunately for the HMR fans, CCI is now making this ammo for them as well.
Additional Update: Â Federal is now loading the bullet for the .22 Hornet cartridge. Â This load uses a 30 grain bullet, likely identical to the 22 WMR bullet, and makes for 3150 fps at the muzzle. Â With this addition, there are now a total of six different loads using these TNT bullets. Â Growth is always good for a line of ammo.
If you’ve had any experiences with this ammunition, would you please leave a review of it in the comments? Â I know that the readers would like to hear first hand experiences with these loads.
