I have a ruger blackhawk that has over sized chambers. I tried .454 dia. hard cast bullets and the accuracy is better. But I still get a lot of leading. Some one advised i get some softer bullets. Anyone out there have any cast .454 in a 255 gr. weight. i would like to find some that are about 15 or so the ones i have are 20 or 21.
