It is lead free day here at The Firearm Blog*, this being the second lead-free ammo post!
Winchester has announced a new line of lead-free ammunition.
CCI currently manufactures lead free .22 Magnum called TNT GREEN but as far as I know Winchester are the first US manufacturer to announce lead free .22 LR. It is rumored that more companies will unveil their lead free rimfire at SHOT 2009.
The new Winchester SUPER-X .22 Long Rifle will propel a 30 grain THP (tin hollow point) at 1650 fps. This is a hot “hyper velocity” load which generates 181 foot pounds of energy, only slightly less powerful that the CCI Stinger at the muzzle.
It is likely that the case will be extended in length, like the CCI Stringer. The extended case can prevent the round from chambering in some rifles.

The new SUPER-X .22 Win. Mag (.22 Magnum / .22 WMR) pushes a 28 grain JHP at 2200 fps. The under 30 grain bullet means it will won’t perform as well as standard .22 Magnum 30 grain rounds.
SUPER-X .223 Rem lead-free pushes a 55 grain bullet at 3030 fps. Like the .22 Magnum, there is a significant performance hit. The round is being marketed as varmint cartridge..
This new range should be available in Spring 2009.
* That was a joke. I bought 100 rounds of “toxic” ammo today.
