Patternmaster code black with nitros?

[TheSportsman]

Has anyone done any testing with the pm code black and the nitros? I've got a rhino .660 in my benelli sbe 1. Was considering trying one to see if it'll out do the rhino with the 3.5" nitro 4x5x7 2 1/4oz loads. What y'all think? Guess all I can do is try it.

I've used my pattern master with winchster long beard and its a real killer

I've never tried them thru that choke, but the ones I've shot do pattern better for me out of a tighter choke than Nitro recommends.
