question concerning one of your molds...

[myronman3]

a while back i picked up a 44 mold from graybeard.   it is far and away my faovrite mold.    i started another thread in the cast bullet forum,  and was advised to come straight to you and ask. 
   during my last casting, i was around bullet 700 when my mold started to make bullets a little bigger, i then noticed it wasnt closing completely.   i stopped casting,  let the mold cool and inspected it,  and sure enough, a tiny bit of hot lead made it's way onto the mold and that was the root of the problem.  i cleaned it up.  when i close the mold,  and hold it up to the light to see if i can see any light seeping through, i can see a super fine hairline of light where the mold comes together. i used a tooth brush to clean  the surfaces and took my sweet time to do it.  as far as i can tell,  the surfaces are clean.
my question is,  is this normal?  any thoughts, observations, or suggestions about it?   i am all ears.  thanks in advance for your help,  and again,  i really like your mold.  after tax season i intend on getting a mold for the 30-30 from you; which will be my first rifle bullet mold adventure.

  Right on.  ALWAYS jump my case if you have a problem with an LBT product.  I MUST keep you happy or you won't come back, and my belt is running in next to the last notch now, so I don't want the dinner table empty!

  I'm quite certain you got hold of me on this one and solved the problem yourself, but didn't tell me what the problem was caused by.  If not, email me at
LBTisAccuracy@Imbris.net            and we'll ferret the problem out or I'll fix the mold.  Whichever works best.

i got it pretty clean,  i believe some lead got on the mold surfice.  i think i got it all.  this mold was flawless when i got it so i doubt seriously that it is defective. 

   when i hold it up to the light, i can see the tiniest bit of light in one cavity, the one furthest away from the handles.  if i push the bottom of the mold together with my fingers (on the cold mold obviously,lol) the light is gone.  upon opening the mold and closing it, the light is back in that cavity.  do i need to adjust the pins out?  keep in mind, the light i see is VERY little,  the angle has to be just right.   
  i was just looking for any insight you might have, to pick your brain.  hopefully you arent getting too skinny.

  Pick my brain?  Guess you didn't know I'm a foggy headed old man pushing 70, huh?

  Till the mold gets well broke in and stays closed with minimum handle pressure, squeeze the handles hard enough to eliminate all that light,  DURING the cast.  After perhaps 300 to 500 casts the pins will seat in with a VERY wide contact area, about 100 times as wide as any competition, and if kept lubricated as needed the alignment will stay within a few ten thousandths roundness for the rest of your life.  I would estimate that after 300,000 casts it will still cast more round than any competitor mold as it comes from the factory.   In other words, there are many mold makers out there who make usable molds, but no one competes with LBT.

  However, for my customers to obtain what they paid for they have to ask questions when they have any kind of problem.  Thanks for asking.
