I've put over 700 rounds of the 125 grain lead bullets through my 995 and over 400 rounds through my C9 with no leading problems. I'm using the Lee 125 grain RN bullet from the 6-cavity 356-125-2R mold. It's accurate and feeds just like its FMJ counterpart. I'm hoping to get the 120 grain TC mold for it soon.
BTW, lead fouling cleans easier than copper fouling, plus lead gives longer barrel life than copper.
