I was going to buy a knight but tried to get a hold of them. I had the same luck as you 12+ calls with no call back or answer. This was last year. Finally got to talk to some of the higher up guys and they said they were going to get more people to help with that. Sounds like it didn't happen.
I shot my muzzleloader for the first time last Wednesday i had 2 types of bullets both shockwaves one 250 grains one 300 grains. I shot 100 grains of powder with both and found the 250 grain bullets to be dead on at 100 yards with out moving anything on my gun. It made my bullet and load choice very easy.
