I have same set up with a sumtoy 562-5. It averages about 160 with fed 7s. I've had some as high as 185 and some as low as 150.
It likes federal heavyweight 6s out of a pure gold tempest 570......puts up 120 patterns with 6s.
Same sumtoy choke with TSS #9 is about 280 in ten
It did not like pure gold 555 tempest, 555 Swarm, regular 570 pure gold, Indian creek( which is odd) , 550 ssx, or sumtoy 575. These chokes all produced patterns with federal 7s from about 75 to 110.
