I ran a few rounds of Winchester LB 3" 5's through my SBE2 today. I was shooting a .665 IC choke. I fired all of the shots from my knee while sitting like I was hunting. The patterns turned out pretty good in my opinion. The 30 Yard shot was a little low but it was probably just me pulling the shot a little. I have tried 3" 5's and 6's and the 3 1/2" 5's and 6's. The 3" 5's were the best about being POI=POA.

Looks good..I get great results with the 6's too with my sbe2 and a hevi .667 choke.
I shot the #5 as well in my Browning and like the way they shoot, going to try a box of 6's this weekend to see if I can get some shot out in that 16-18" "Halo".
Ditch the turkey head targets and shoot @ 3'x3' paper....it will give u MUCH more feedback than a turkey head target!!!
The 3" 6 LBs shot phenomenal outta my SuperVinci!
