I have shot the BB 180 gr hard cast in .357 mag and find this ammo to be accurate and also punishing with a revolver. In my lever Rossi M92 in .357/.38, it is very accurate and a powerfull performer. It is still a 100 yard rifle for deer and unless one upgrades the factory sights, even this range is difficult without a good rest. Buffalo Bore has a excellent reputation and produces good ammo.
