Lube prices are actually $35 for 10 sticks, plus $6.30 shipping in the US, or $85 for 30 sticks, plus $7.90 shiping. The catalog should have the prices posted fairly soon.
In 25 years of mold making, I have yet to have a customer report less accuracy from a two or four cavity LBT mold than from a single cavity. (I used to make 1 cavity but no longer do it.) ( Cherry cut molds can't duplicate this reputation.)
Bullet length is limited to 1 3/8 inch, which makes pointy 45 caliber maximum weights just a little over 500 gr. Bore ride nose bullets are fine with black powder if you use the traditional soft alloys and balance hardness to the powder charge till accuracy peaks. At this point, if fired bullets are recovered without to much impact damage.(easy from snow, if picked up in the spring) you will find that the entire body has expanded to groove diameter. Because of this upset, pointed bore ride nose bullets will slump back with the nose off center and out of balance, while the traditional round nose forms will produce a straight cylinder with a blunt and quite well balanced ball up front. The good balance is why such bullets turn in exceptional accuracy, but the blunt form caused excessive air drag. Because the bore ride nose has to slump to fill the grooves to get accuracy, and the main purpose of having the BR nose is to allow chambering in spite of powder fouling, BR noses on this type bullet should be fitted a good .010 smaller than bore, or there will be no chambering advantage.
Customer reports (I have no experiance with black powder cartridge loads.) indicate the best long range accuracy is obtained with straight bodied bullets at full groove diameter, with enough hardness to prevent bullet slump, or obturation, thus maintaining near perfect balance. Such a bullet in the heavier weights requires rethroating most 45-70 rifles to allow seating out so enough powder can be used to get speed up to desired levels. Also the throat will have to be swept out as needed to allow the close fitting bullet to chamber.
