Baboon - is that a Great Dane in your avatar? I have a rescue dane from Paws of Austin as well as a rescue dobie from Brazos Valley Doberman Rescue - both are great dogs!
Cast bullets that are lubed can add to a bit of smoke. For the price they are hard to beat. I started reloading Laser Cast & found Missouri Bullets for alot cheaper. I have yet to load up the Missouri's, with the heat on now it could be a while.
If they lead up, it's an issue of an overly-hot load, IMO - or too soft a cast projectile. Most folks wanna run "hot" loads so they can "macho up" at the range. Me, ah just wanna cut consistent holes in the paper....
