I recently purchased a Gen 2 72 caliber Zeus with the 16 inch barrel from Fox Air Power. Great customer service and I would not hesitate to order from them again. I have been experimenting with different projectiles and it likes the Mr. Hollopoint 440 grain slugs at 900 fps. I get that with a 4000 psi fill. I am getting three good shots that will usually touch at fifty yards, which bring it down to around 2200 psi. At 100 yards the second and third shot will drop an inch or so from the first shot as the velocity slows, but it is very predictable. As it is early squirrel season here in Mississippi I wanted to give the Zeus a try. I set up fifty yards from the corn cob feeder and managed to take a squirrel on my third try. I will link the video below. I was pleasantly surprised at the minimal meat damage. Looking forward to deer season to give it a try.
