Wondering why the Sherman short and tactical version are not more popular. Rich has got ready to go ADG brass and dies. Not really even a wildcat anymore. It does everything better than the PRC and SAUM. Better velocity, better COAL, and supposedly has better barrel life (not sure if i buy the barrel life claim). There are even a few companies doing pre fits for the shermans. What am I missing? Aside from factory ammo options....
