I have been using .357 wadcutters in 38 special cases and in a rifle for back yard plinking and pest control. I have it zeroed at 25 yards and the longest shot was at 35 yards. I do not know if much beyond that, it would kill a small critter (raccoon or woodchuck) with authority (bang-flop). I do know they are not a pass through at 35 yards, but it does drop them quickly. If shot into the ground (my backyard) at a shallow angle, they do not ricochet, I have recovered them, just under the grass.
