I shoot more 38 wadcutters than anything else. They are accurate, soft shooting and easy to put together. The only rub is that in my favorite revolver they tend to lead (shortly after the forcing cone). Consequently, I spend extra time cleaning after range visits. Several extra passes with the boresnake gets it out, but of course I would rather not have to. I will probably start troubleshooting (first is to try making some up without the Lee factory crimp die, suspect it may be swaging down a bit inside the case), but before I start doing so it occurred to me to wonder if I should just deal with the extra cleaning and leave well enough alone. What amount of leading do you consider acceptable?
