I decided to lap an old mould to better fit a new (to me) 1898 Krag rifle.  The victim was a Lee C309-200-R, single cavity.  After lapping I scrubbed the cavity with hot soapy water, then rinsed in hot water.  After drying the mould on the back of the pot I dipped the corner in the molten lead (as recommended by Lee) and started casting bullets.  (I seem to remember the recommended time for dipping the corner of the mould in the lead was 8 seconds, but the instructions with my new mould say at least 30 seconds, but the pictures are of a 6-cavity mould, even thought they came with a 2-cavity mould.  Whatever.)  They were pretty wrinkly, so I smoked the cavity, which didn't help much.

So I thought, "Let's burn that grease out!"  (The valve grinding compound used to lap the mould is in a grease carrier.)  So I dipped the corner of the mould in the molten lead and waited.  After about 30 seconds it started to smoke.  It smoked for about a minute and a half (still in the lead), and I left it for about a minute more. 

Just for grins I filled the cavity.  It took about a minute for the sprue to solidify.  Yeah, it was hot!  The ejected bullet was quite frosty.  I let the mould cool to "normal" casting temperature and proceed to cast a handful of bullets.  No more wrinkles.  I'll add a photo when I figure it out....
