Congrats on trying a LEE bottom pour, I have been using the same LEE BP pot since 1977, I have the Higher version, that lets me use 4 and 6 cavity molds.
I believe thr rough boolits you were talking about are what is commonly called Frosted, did they look like they were covered with frost? This is caused by the mould getting Hot! You are casting RBs so you don't need to run this hot. try using two molds at the same time alowing one to cool with the ball still in it, while you fill the other mold, just keep routateing them.
Your WWs will make a good ball but it will be slightly harder that pure lead, this will almost always gaurantee complete pass threw. I have harvested a lot of deer in the past with a .45 RB, if i casted them of lead I almost always could recover the ball, if they were WWs complete pass threw every time. I have two 35MM film containers full of recovered .45 RBs from deer down in my colection of prizes in the shop.
If you ever felt a need to harden your Balls

, just run the mold hot to you get frosting and then drop the ball from the mold into a bucket of water, this is how I cast my 333 gr. LBT LFN Boolitzs for us with sabots. To keep spashing down or nonexistant, use a sponge floating on the water and drop the boolit onto it, or cover the serface of the water with foam rubber peanuts.
Your WWs are of value to myself and other casters, some of use would even trade you pure for WWs, and with the USPS flat rate box yo can ship then any were, up to 70 lbs for as little as $4.95 to max of $12.00
A friend In Alaska sent me 45 LBS of WWs for the Hard cast I sent him
