SpeedyR lived up to his name, or you'd have another buyer, brown42! Another plug for Castboolits.com, an addictively large supply of casting info there. Just like here, find the forum you want, then use the Search feature to find all the hidden "gold"!
For example, you might consider hardening your cast bullets yourself. If you like the price of the ones you already use, why look for more? Procedures for baking in an oven to harden can be found on the Castboolits site, and much, much more!
Dang SpeedyR! There are no flies on you! Hey didn't the lady of the house give you that name?
