I shoot a 21" 11-87 with .665 jellyhead with 3" #5 LB and do 180s in 10" at 40. My 26" M1 benelli does around 190 with a carlsons .650 with the same shell. M2 benelli did 180 with Indian Creek .665. I have patterns posted of the m2 and 11-87. I tried the #6 LB but my guns didnt like them. My friends gun loves the 6s. Hope this helps and good luck
