I have been shooting the 358 Bullberry for over 35 years. I have it in a contender pistol and rifle and a Handi rifle. Killed many a deer with them. The only difference is the buckhammer is shortened to 1.8 inches per regulations and the Bullberry round is full length case and slightly bottle necked which does not meet those state requirements. The ballistics are really about the same. Those states that have these requirements do not allow cartridges such as the 38.55 or .375 win. Those cases however can be used to form the buckhammer.
