Went to the range today to fire my 1187 20 ga with 21" barrel.  Wanted to try different chokes and loads to see what works best for me.
I got more-than-acceptable hunting patterns with both Federal TSS 1.5 oz #9s at 1100 FPS, as well as Hevi 1.25 oz #7s at 1090 FPS, at ranges varying from 20 to 40 yards.  Using a Carlson's .575 turkey choke.  
I noticed a LOT more recoil in the little gun with the TSS loads.  The difference, at least to my shoulder, was pretty extreme.  Am I just imagining things?  Has anyone else noticed a harder kick from the TSS?
