As my user name implies, I am familiar with the .243 diameter version of this wildcat. Fun times, but wouldn't necessarily be a proponent of such. Live in the Communistwealth of VA. Shooting has been a huge part of my life, kind of got stuck in a situation where I didn't have much space for tinkering and reloading, but have managed to rectify that. Kind of wish I would have stocked up on some extra powder back when, but oh well. Here is to some great discussions.
