You didn' t say anything wrong Smokem , some folks may not know much about the round your question deals with . I' ve seen the .454 Casull demonstrated , and I have no doubt that it could take out a grizzly . If the cartridge is legal where you live then try it out . Get lots of practice with it first .

I' ve noticed that some folks on here don' t seem to care for pistol hunting , I don' t happen to be one of them although I don' t pistol hunt .
