Actually, in my experience good quality lead bullets are as accurrate as jacketed. In an effort to save $$ and stay in the game when time were tight, I shot lead bullets from a local guy who made/makes top shelf stuff. It shot SOFTER than jacketed, and I could easily put a cluster of shots the size of my palm into the "A" zone at 50 meters, off-hand. The problem is the smoke. It can be very difficult to see through when shooting at speed, and it is of course comprised in part of vapourized lead particulate, which is poisonous. It is less dangerous out doors, but it is also less competitive. It is also a lot more troublesome to clean out of your bore.
