I wanted to bring back this topic as I believe Dan is now back in operation at a new location.
I've pm'd him over at Cast Boolits to see if he can provide a more accurate description of what he has to choose from currently. Hopefully will be updating the pictured bullets in the near future.
Current info that I do know is shown below so far as contact info. I believe he simply needs you to email what you would like, he will respond about availability and provide pricing info.
For any of you that are not familiar, Dan makes some of the finest lubed conicals for muzzleloaders to be found - and his prices have always been very reasonable.
