I was very pleased with the numbers. With the ssx and feds I am getting 180-200 consistently. The cleaner the barrel the better the patterns.
this same combo with hevi 7's was putting up in the 150's. 156 was my best with hevi. Which is still a killer pattern but hard to beat 200. A lot of 12's won't even do that. My 1187 SM with winchester HV 3.5" 6's put up 192 from my notes. That's 12 ga performance in a 20ga load. More down range energy due to the 15g/cc
