Well, after reading about Blackhorn 209, I can report that I fired 20 rounds with no cleaning of the bore or breech plug in my Traditions Vortek. I used the BH volume cylinders with 110 grains of powder, CCI 209 magnum primers and Traditions Smackdown 250gr sabots. The only issue I had was with shot # 19, which was a delay fire. The primer was also blackened so I suspect the primer and fired shot # 20 with no problem. Good performance from the BH and the Vortek. I will definately be using BH 209 with CCI magnum primers and probably hornady sst sabots. Not a lot of smoke either, although not as clean as smokless. A little pricey though but worth the money in my opinion. I also had no problem finger screwing the breech plug out.
