I have a Valkyrie, but haven't messed with it much. I like it so far though. I won't take the CM route because they seem to be stealing Wildcats from people and calling it their own. The 22cm is a 22/243 that has been around for years. The 6 cm is a 6mm Rem ripoff basically and the new 8.3mm is from what I have hear a stolen .338 Federal. I don't like thieves so I will stick with a .260, the Real 6.5...the Swede, or the 6.5 PRC.
