Call me confused. I just started to cast my own 45 bullets with a Lyman mold, 220 grain round nose bullet, single lube groove. I have both the .451 and .452 sizers so I am OK either way on this. Most, if not all of the lead bullets I have seen commercially are .452.
Then I read in my Lyman book, page 380, "Groove diameters can vary from .450" to .453" but the shooter should not size cast bullets larger than .451" due to chamber dimensions."
I want to limit the potential to leading and understood that with lead, an extra .001 was ideal. So before I prep several hundred of these, what is the correct answer?
