you don't see any wildcats (that I know) of, based on the 7mm Rem Mag? The quick answer, I know, usually is that it is duplicated with a "standard" round. What .243 round is out there that would that would duplicate a 7mag necked down to .243 and twisted to shoot 105/108gr bullets? Other than a short barrel life and people's misguided concerns about "belted" brass what down sides would I run into? Thanks for any in put.
