Another question from a newbie. My wife bought a Smith & Wesson model 60 Lady Smith in 357 mag. I bought some reloaded 148 gr. HBWC in 38 SPL for her for target practice but found that they fouled the cylinder with a lot of lead which I am still trying to clean up. Can I load 357 brass with a bulky powder and SWC bullets to 38 SPL pressures safely? Would this push the bullet out further and decrease the lead fouling of the cylinder?
