I just read an article on this caliber and it's not for handloaders. Aparently the powder they use to get their spectacular velocity is not avalible to the public, and without it you won't be able to match factory ammo. There isn't a real need for a varmint cartridge that you can't load up to its full potential.IMHO The field is pretty full with the 17 REM and the .223. If you want more power the 22-250 or 220 Swift.
