I was casting both RCBS and Cramer (looks like the Lee 148gr. button nose WC) wadcutters earlier today, but was less than thrilled with the prospect of using the Cramer again because of a poorly filled out front portion. And yes, I've tried casting at different rates, temperatures, with the ladle in contact/not in contact with the sprue plate, venting the mold as per Ben's method, to no avail. Just by chance, the metal fixture which exerts downward pressure on the sprue plate was loose, and thus not functioning, but the result was an immediate improvement in fill out: practically no rejects afterwards! While it's tempting to remove the thing altogether, it's not a good idea as it acts as a stop for the sprue plate, so I'll leave it loose and ineffective. To me, Cramer's idea was a solution that created a problem and it only took me 10 or more years to discover it!
