With a 1 1/8 oz payload, 1100 fps would do fine at the 16 yard line. I would not think they would function an auto and they might even be too light for some inertia triggers. Load some, try some. That would give you a good idea if they work for you. I don't think the difference in recoil would be that great, but I'm not recoil sensitive to begin with. I run both 1oz and 1 1/8oz loads at around 1150 and they work just fine. In really cold weather, they will lose a little velocity. They still work fine, despite the loss of s bit of velocity.
