Hi, I have an itch for a 6mm TCU but looking at the list from MGM they have a 6mm Vartarg Turbo I believe is based on the 222 Rem. mag brass but not sure if there are any other changes other than necking up and wondering if there might be a bit more powder capacity for a bit more velocity. Anybody have one or know anything else about them? I will be using it mainly for coyotes but also for deer hunting. I know alot of people have shot deer with the 6mm TCU and others say it is not enough but I only take through the ribs shots. Also do you know if MGM can get dies for their wildcats. All thoughts appreciated, thanks.
