Well, not so sure my homemade lube is all that good. I cleaned the bore yesterday and found some lead. Only one sliver, but lots of tiny flecks. Now those small bullets could have been the contributors to this. I can see the lands shearing lead off the bullet since they only had 0.0005 engagement. Cleaned it of any lead and gave it a quick lap with JB Bore Paste for good measure.
I will keep the lube and when I get this rifle sorted out, I'll try it again to see how it does.
