I make my own with a Lee tumble lube 6 cavity mold, water quenched wheel weights, and Alox lube. works very well over Tightgroup. 175gr Semi Truncated in 40cal.
Leading is not bad at all. I run a tight brass brush every 3 to 4 mags and that keeps everything happy. Very accurate and shoots POA. Duplicates jacketed ballistics.
If your lead bullets are tumbling, odds are you are using the wrong bullet or have massive leading. You need hard cast especially in the 9mm. The larger the bore, the softer the lead tolerated (rule of thumb) IF the bullet is a proper fit to the bore/throad.
