I shot almost 2 boxes of the Federal TSS 3.5" 12G #9's out of my SBEII trying to get a pattern i was happy with. I tried the primos jellyhead .660, kicks .665, Trulock TSS .640, Trulock TSS .650, and an Indian Creek .665. The Indian Creek outperformed them all. I'm not happy with the pattern yet because others are stating they are getting 400+ pellets in a 10" ring at 40yds. The best i got was around 350 pellets. I would like to try a .670 or .675 to see if it gets any better, but i'm gonna stick with the Indian Creek .665 for this season until i start handloading some of my own, then i'll tinker with it some more.
