I shoot similar 1 1/8 loads from my 6# 16 gauge. I wouldn't want to shoot a round of skeet with them, but a few while pheasant hunting are not that bad.

I just wanted to know if I needed some extra oomph late in the season if the gun could handle that.

Btw the recoil energy in that set up would be about 38.5 ft#s 10 ft#s less than my standard goose set up. In no way am I saying those numbers are pleasant. However I do handle those goose loads fine.
