Since Remington done the developement work and introduced it as the 6.8 Remington SPC,it does not fit the definition of a "Wildcat" cartridge.
The .270Win.,the .444Marlin were factory designed and developed from the 30-06 case,the 10mm auto was a shortened .30 Rem. case yet none would consider them to be wildcats.
Remington has a gov't contract to produce 10 million 6.8 Rem.Spc cartridges in 2004.They are offering 2 different civilian loads in 2004.
Barrett is produceing AR 15 uppers in 6.8 Rem.SPC at this time.
As a sporting cartridge in an AR-15,it will probably be a success,for other types of firearms there are a lot of better .277 caliber wildcats.If cheap surplus ammo becomes availible that might change the picture.
