For most of my guns including a 308 Ishapore lead is all I shoot. Go with Penn bullets and keep the hand gun bullets under 1000 FPS and there is very little lead. These are cast and hard cast bullets. He also makes a Premium grade that I use for rifle 44 magnum rifle which is good for 1600 FPS and this is without gas checks.
I think your worrying about leading to much if you use a slow powder and use moderate speed.
They also make a good bore cleaners that helps take out the lead.
The photo is a Penn bullet.
