50-70 / 50-90 Boolits

[Good Cheer]

Anyone shooting boolits from 50-70 and 50-90 type molds in their muzzleloaders?
What bore diameter and twist are you using?
What kind of accuracy are you getting?

I was when I had a Green Mountain LRH barrel on a Renegade, and had a Ruger 77/50. I've since sold both. The Lee 50 caliber bullets worked fairly well but even better was the RCBS bullet designed for the 500 S&W since it is almost the right size to start with. If you use the 50-70 type bullets, fill the lube grooves first before you size them so there is some groove left afterward. If cast from pure lead, they are easy to size down in a Lee push through die.
I think bore diameter on those was .500 or maybe .501, twist probably 1:28, and accuracy was only limited by my eyesight. pretty much all touching at 50 yards and maybe 1.5 - 2 inches at 100. I also had good results with a .492" NEI mold I have paper patched.
