I know slugs are the cool thing to shoot and I've messed around with them too but you don't really need them for rabbits. I think I used my little 18 fpe Prod for the last one I killed. Worked fine. You could lower your regulator to shoot lighter weight pellets and gain shot count but if you don't want to I would stick with the ones that don't go faster than about 925 fps. I just shot a nice target this evening with cheap old Crosman 14.3s at 925 fps from my Bullshark. They would drop a rabbit very quickly. But so will a 20-25 grain pellet. You might want to add H&N Baracuda 21 grain to your list if you don't find a winner from what you already have. They shoot the best from my P35-22. I killed a small raccoon with them (and 10 squirrels so far, all DRT).
