It's rifle calibers that get leading with cast bullets. Handguns just don't go fast enough to cause problems.The problem is most guns made in the last 20+ years are actually setup for jacketed bullets, revolvers especially, but autos too with polygonal rifling and such. A cast lead bullet needs to be BIGGER than the barrel it gets shoved into in order to seal. Chamber throats aren't machined for this they are sized for jacketed. When's the last time you saw centerfire lead bullets for sale in a common for today caliber? That's why...A coated lead bullet will run fine in a Glock barrel as far as leading goes but generally won't be as accurate. If you stuff a .357 dia bullet in it it may match a jacketed for accuracy. New barrels made today have generally shallower rifling than in days gone by. That's another why...It takes some work to get all the stars to line up with lead bullets these days. Used to be you could just slug your barrel and use the right size bullet and then find your load. Now seems to require a gunsmith to work on the chamber.</blockquote>
