Update:
As it has been six months since TOW placed an order for the .526 RB molds I sent an inquiry to Lee regarding the status and their response follows below.
We are still getting caught up with our standard production buckshot and 6 cavity molds, so it will most likely be mid-summer before we start on the custom six cavity roundball molds that Track of the Wolf has placed.
Thank you.
Sincerely,

I am anxious to acquire one of these molds as the .526 diameter has provided a solution to my accuracy issues with the latest built Isaac Haines with swamped Rice barrel. Over the past several months using .530 balls, I've tried patch thicknesses between .010" - .015" , muslin and twill, 2F and 3F, 80 to 110 grain charges and all with mediocre results. With .013" to .015" patching, the ramming is a bit too stiff, especially after a couple of shots and fliers have been too common an occurrence for full hunting confidence. With stiff loading I presume that patches may be getting over stressed and the fibers perhaps separated on the way down the pipe. Recovered patches are intact but quite frayed. I am very happy with this rifle but the accuracy has been a source of distress and frustration.
NOW.....( drum roll ).... with the .526 balls purchased from TOW, .015" fabric from Eastern Maine Shooting Supplies, greased with mutton tallow, over 100 grains Swiss 2F, I'm suddenly getting delightful one hole groups at 50 yards. I'm over the moon with these results - but the purchased balls are .40 cents a shot and I much prefer the independence afforded by mine own bullet casting. Can't wait for the new molds to come in.
