303 Brit then a year or two later I got a Rossi revolver in ss 6 inch 357. I remember shooting jacked bullets and wanting something cheaper so I bought a box of 500 hard cast for 11$. I remember the accuracy was terrible and the bore was so leaded it was a smooth bore. I gave up on lead bullets then and only shot lead in muzzle loaders. About 96 or so I started loading for 380 acp I also bought a 500 box of hard cast 8 or 9$ they shot fine no leading and actually shot real good out to 25 yards in the cheep pistols I was using . Accuracy I thought was decent probably 6 in . They where way more accurate than the 357. Back then I didint have internet to find out what was causing the leading in the 357
