.45 super disc loads

I just bought a new .45 super disc in SS. According to the literature it can be loaded with 150gr of pellets but only 120gr of loose powder.

But it also says in several different places that it will take 150gr of pellets or the equivelent of black powder or substitute. I've been trying to figure what is the real story!

I have a .50 CVA that I shoot 150gr of loose powder without any problems, HELP! Whats the scoop, or is Knitht just promoting their own agenda's and will any 150gr work well?



Though I was born to royalty, I was snatched at birth, so treat me as the noble I am!!!
