Holy Toledo! (Sorry, I just had to get that out of my system)
Am not familiar with the name, but I can say that the T/C Barrels with 1 in 66" twist have been very accurate, and owners have won state & national matches with them. Hard to beat the factory issue!
For a few years, T/C offered a .40 caliber in a rifle named after National Champion shooter, M. Cleland .
The .40 caliber is INHO, like a .243 Win. Fast, flat-shooting, and accurate out to 100 yards+.
My Watts flintlock is a .40 caliber.
Sorry, not much help.
