it makes great "looking" 170 and 210 gr. JHC 0.401" bullets for me. I have squished a lead core before and it made a bit mash out but it did not seem loose. The bullets do become longer.
It's about as far as you can go sizing down, 0.010". I's much easier taking .311-.314 to .308, .360 to .358-.355 etc. My .38-55 mould throws .380" bullets. So I mash them to .376". I think a lot of old .38-55's had oversize bores. Some old .38/40 ran 0.403" too.
I've done a bunch of cast .41 to .401, it can rub the grease grooves pretty good. You should see the bag of home made Paco Kelly bullets I ended up with, it is a wonderous study in itself.
